| Abstract: | 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. |
