摘要
目前很多早期修建的高速公路服务水平明显下降,高速公路扩建、扩容将成为工程重点。以京港澳高速公路扩建为背景,介绍了扩建工程中桥梁设计的关键技术问题,与同行共同探讨。
At present, the service level of many expressway constructed in early time has decreased obviously, therefore, highway expansion and rebuilding becomes point engineering. Taking Beijing-Hongkong-Macao highway as an example, this paper introduces some key techniques of bridge design in highway rebuilding and expansion.
