一种特殊结构桥梁排水的创新设计

Innovative Drainage Design for Bridge with Special Structure

针对在特殊地形地质情况下高速公路与已建成高速铁路交叉,致使高速公路的设计标高不满足百年一遇防洪水位的要求,在重庆铜合高速公路金九大桥采用了特殊的结构设计和集中的防排水措施,并为排水系统制定了独立的养护方案及应急预案,为解决在类似环境下高速公路与高速铁路交叉提供了新的思路。

Because of the grade separation of the expressway and the existing high-speed railway under special terrain and geological conditions,the designed elevation of the expressway does not meet the requirements of flood control.The Jinjiu Bridge on Tonghe Expressway in Chongqing adopted special structural design and centralized water-proof and drainage measures,and an independent maintenance and emergency plan for the drainage system was made,which provides new ideas for solving the grade separation of highway and high-speed railway in similar circumstances.
