Design Essentials of Bridge in Reconstruction Project

摘要:

城市道路随着城市快速发展和汽车保有量的极速增加，原有的道路通行能力、舒适性、经济性变差，已经不能适应城市发展需要，为改善城市基础设施，提高居民通行质量，节约出行时间成本，道路改造成为城市市政工程中主要组成部分。其中水系发达的南方城市，道路中包含多座桥梁。桥梁改建又是道路改建中的重要环节和决定性节点和难点，因此改建道路中处理好桥梁改建尤为重要。

In order to improve the urban infrastructure, improve the quality of traffic for the residents, and save the travel time and cost, the road reconstruction has become the main part of urban municipal engineering. There are many bridges in the roads in the southern cities with the developed water system. The bridge reconstruction is also an important link, decisive node and difficulty in the road reconstruction.
