过去的十五年中,中国开展了全球最大规模的公路基础设施建设,桥梁技术得到快速发展。这时期,修建公路91万公里(其中高速公路4.1万公里),占2005年底193万公里公路总里程的44%;修建的桥梁数和桥梁合计长度分别占2005年底33.7万总座数和1.47万公里总长度的47%和66%。大跨径桥梁建设遍地开花,公路桥梁主跨于1991年突破400米之后,1999年跨径又突破了1000米。十五年的时间里,我们已建成主跨400米以上的桥梁30多座,最大跨径达到了1490米。桥梁类型之多、跨径突破之大、技术进步之快令世界为之瞠目……
Over the past 15 years, China has carried out the construction of the world’s largest highway infrastructure and the bridge technology has been rapidly developed. During this period, 910,000 km of highways (including 41,000 km of expressways) were built, accounting for 44% of the total mileage of 1.93 million km by the end of 2005; the total number of bridges constructed and the total length of bridges accounted for 337,000 seats and 14,700 respectively at the end of 2005 47% and 66% of the total length of the kilometer. The construction of large-span bridges began to flourish. After the main span of the highway bridges and bridges broke through 400 meters in 1991, the span span exceeded 1,000 meters in 1999. In the past 15 years, we have built more than 30 bridges with a main span of 400 meters and a maximum span of 1,490 meters. As many types of bridges, great breakthroughs in spanning distances, rapid progress in technology make the world astonishing ...
