美国城市道路及桥梁工程考察的回顾和思考（1）

20世纪90年代中期正值北京城市道路交通及桥梁工程建设快速发展的时期,在二、三环实现快速环路、全立交建设的基础上,计划继续实施四、五环市政道桥工程。因此,为了学习、了解和借鉴国外相关的先进技术以及道桥建设和设计的相关情况,北京市市政工程设计研究总院组成赴美考察团,对美国6个州8个城市进行了城市道路、高速公路和桥梁的实地参观、考察,掌握了很好的、详实的一手资料。本文根据当时的资料,从总体印象、具体工程、设计情况等方面分段陈述当时美国道桥建设的总体印象,并提出了若干思考和建议,以期为目前我国仍然方兴未艾的城市道桥工程建设提供有益的参考。

Review and Under Standing on a Study Tour of American Urban Road Bridge Engineering

For ninty years of 20 century,Beijing urban road traffic and bridge engineering construction had been developed rapidly,the 2nd and 3rd ring road and interchangs were constructed and the 4th and 5th ring road and bridges are scheduled to be constructed continuously.Thus a study tour was organized by Beijing General Municipal Engineering Design and Research Institute,and urban road express way and bridge of 6 states 8 cities of America had been studied in spot and got to know well a lot of first hand data and informations.These are available for the refer- ence of urban road bridge construction of our country at that time.
