The Golden Gate Bridge (这个大桥叫“金门大桥”) The Golden Gate Bridge is a suspension bridge spanning over 1,280 meters to connect San Fransisco to the surrounding northern Californian counties. The bridge was the longest suspension bridge in the world at the time of its completion in 1937 up until 1964. The bridge stands 67 meters above the water, with its towers reaching 227 meters above the water. The live load capacity is 1,814.4 kg/lineal foot with a maximum center span downward deflection of 3.3 meters. Each of the 2 main support cables has a diameter of 0.92 meters and is 2,332 meters long. 129,000 kilometers of wire is used in each cable. The Golden Gate Bridge took 4 years to build. Glare-free goggles and an early version of hard hats were used for the first time in the construction of the Golden Gate Bridge. Safety nets were also suspended below the bridge from end to end. The nets saved the lives of 19 men who were from then on known as members of the Half Way to Hell Club. Although 11 men died during the construction of the bridge, this was a distinct improvement over most construction projects of the time. The bridge has been closed on 3 occasions due to extremely high wind speeds, but withstood the onslaughts all 3 times. In 1989 an earthquake measuring 7.1 on the Richter scale forced the San Fransisco / Oakland Bay Bridge to close, but the Golden Gate Bridge was able to stay open. The original paint on the Golden Gate Bridge lasted 27 years until 1965 when concern over the high salt and moisture content in the air became a concern. In 1969 a sand blasting project was initiated to remove the old lead based paint and to repair corrosion. A lead-free primer and top coat were then applied to protect the bridge from corrosion and adhere to environmental regulations. The project was completed in 1996. Recent updates to the Golden Gate Bridge include Seismic Refitting, the installation of a movable barrier between oncoming lanes of traffic, a safety railing, suicide deterrent screens, and cable restoration. 翻译: 金 门 大 桥 金门大桥是跨度超过1280m的悬索桥,它把旧金山和加利副尼亚北部周围的县连接起来,该桥从1937年建成到1964年一直是当时世界上最长的悬索桥。它距离水面67m,其塔高出水面达到227m。活载承载能力为18144kpa/inch,最大中间跨度向下倾斜3.3m。两个支撑的主索每个直径0.92m,长2332m,每个用了129000千米的金属丝。金门大桥的施工用了4年时间。 金门大桥在早期施工阶段采用了(Glare-free goggles and an early version of hard hats ?)施工法,从桥的这端到那端安全网也悬挂在桥的下面,该网救了从那以后被看作是通过公路去地狱俱乐部的19个人的命,但是仍有11人在施工过程中丧生,这相对那时许多建筑工程是一个很明显的进步。 金门大桥由于很大的风速而关闭过3次,但是抵住了所有3次冲击。在1989年一次测量为里氏7.1级地震迫使旧金山/奥克兰海湾桥关闭,然而金门大桥一直能够保持畅通。 金门大桥上原来的油漆持续了27年,一直到1965年考虑到空气中过高的盐分和潮湿的厉害关系,在1969年一个沙滩爆破项目被发动来移除旧的铅装置油漆,并且修补腐蚀的地方。一个释放的铅雷管和顶层油漆随后被装置来保护桥免于侵蚀,并且符合环境规章。该工程于1996年完成。 近来对金门大桥更新材料包括地震的改装,该装置是一个在将来交通的通道、安全的扶手、自杀威慑屏和缆索复位之间可活动的栅栏。

San Francisco San Francisco is an exciting and beautiful city. It rises on a steep, hilly peninsula between the Pacific Ocean and San Francisco Bay in western California. The strait between these two bodies of water is known as the Golden Gate. San Francisco Bay is one of the finest natural harbors in the world. Its port facilities handle much of the West Coast's import and export trade. And the city of San Francisco is often regarded as the gateway to the Far East.San Francisco is important in both banking and insurance. It is also the western headquarters of the communications industry, as well as a variety of manufacturing and processing businesses.San Francisco is the home of about 680,000 people. Together with Oakland, across the bay, it is the center of a metropolitan area of five times that number. San Francisco's population long has been a cross section of the world's. People came from all over the globe, from the east and west, and settled in this cosmopolitan city. More than 60,000 of its citizens are of Chinese origin. Russian Hill was named for the nationality of the people who lived there in early days. There are also many persons of German, Irish, Italian, Mexican, Filipino, and English origin.From the Twin Peaks, which dominate the center of the city, one looks straight down Market Street to the bay. Another magnificent view is from Coit Memorial Tower on Telephone Hill. From there it is possible to see the entrance to the bay, the cities on its eastern side, and the great span of the Golden Gate Bridge.San Francisco's famous Chinatown -- the largest in the United States -- is along Grant Avenue and nearby streets. It is a colorful district of Chinese shops, restaurants, and temples.Institutions of higher education in the city include San Francisco State University and the University of San Francisco. The original campus of the University of California is in Berkeley, just across the bay. Among the city's notable museums are the California Palace of the Legion of Honor, located in a spectacular setting overlooking the Pacific Ocean, and the Museum of Modern Art, in the downtown Civic Center. After having to start this guide the past few years with the announcement that San Francisco is still recovering from the repercussions of the dot.com crash, the terrorist attacks of September 11, 2001, a dramatic influx of new residents (up 13% since the '90s), and the general economic strains of 2002 and 2003, there's great news to report: San Francisco has definitely been on an upswing.Of course, even during harder times, the City by the Bay was still a fantastic place to visit. So much so, in fact, that in late 2004 it was ranked the #1 American city by Condé Nast Traveler readers for the twelfth year in a row.Even if you've never been to San Francisco, you probably already have an idea of some of its classic offerings: stunning bay vistas, Victorian architecture, swank boutiques, killer restaurants, walkable beaches, those oh-so-charming cable cars, the trademark dash of liberalism, and only-in-San Francisco style (remember the gay marriages of 2004?), all of which is tightly tucked into about 7 miles squared. The recent changes -- new restaurants and hotels, renovated museums, an overall sense of optimism -- may not seem apparent to the first-time visitor, but to us locals it's obvious and very welcome: The city feels exciting again.So, what can you expect from the country's most romantic European-style city, which was founded on -- and still revels in -- the pioneers' boom-or-bust lifestyle? Whatever your heart desires! Like an eternal world's fair, it's all happening in San Francisco, and everyone's invited.The Great 1906 San Francisco EarthquakeThe California earthquake of April 18, 1906 ranks as one of the most significant earthquakes of all time. Today, its importance comes more from the wealth of scientific knowledge derived from it than from its sheer size. Rupturing the northernmost 296 miles (477 kilometers) of the San Andreas fault from northwest of San Juan Bautista to the triple junction at Cape Mendocino, the earthquake confounded contemporary geologists with its large, horizontal displacements and great rupture length. Indeed, the significance of the fault and recognition of its large cumulative offset would not be fully appreciated until the advent of plate tectonics more than half a century later. Analysis of the 1906 displacements and strain in the surrounding crust led Reid (1910) to formulate his elastic-rebound theory of the earthquake source, which remains today the principal model of the earthquake cycle. At almost precisely 5:12 a.m., local time, a foreshock occurred with sufficient force to be felt widely throughout the San Francisco Bay area. The great earthquake broke loose some 20 to 25 seconds later, with an epicenter near San Francisco. Violent shocks punctuated the strong shaking which lasted some 45 to 60 seconds. The earthquake was felt from southern Oregon to south of Los Angeles and inland as far as central Nevada. The highest Modified Mercalli Intensities (MMI's) of VII to IX paralleled the length of the rupture, extending as far as 80 kilometers inland from the fault trace. One important characteristic of the shaking intensity noted in Lawson's (1908) report was the clear correlation of intensity with underlying geologic conditions. Areas situated in sediment-filled valleys sustained stronger shaking than nearby bedrock sites, and the strongest shaking occurred in areas where ground reclaimed from San Francisco Bay failed in the earthquake. Modern seismic-zonation practice accounts for the differences in seismic hazard posed by varying geologic conditions. As a basic reference about the earthquake and the damage it caused, geologic observations of the fault rupture and shaking effects, and other consequences of the earthquake, the Lawson (1908) report remains the authoritative work, as well as arguably the most important study of a single earthquake. In the public's mind, this earthquake is perhaps remembered most for the fire it spawned in San Francisco, giving it the somewhat misleading appellation of the "San Francisco earthquake". Shaking damage, however, was equally severe in many other places along the fault rupture. The frequently quoted value of 700 deaths caused by the earthquake and fire is now believed to underestimate the total loss of life by a factor of 3 or 4. Most of the fatalities occurred in San Francisco, and 189 were reported elsewhere.
