摘　　要：随着城市多系统立体交通的快速化建设,在上层交通系统建设过程中其承台基坑设计需考虑的环境因素较为复杂,边界条件较为苛刻。本文以上海某高速公路改建项目的承台基坑工程为背景,介绍通过合理的基坑支护设计方案,解决基坑开挖过程中对现状通行高速公路及地面道路位移、沉降控制的难题,确保道路通行的安全。With the rapid construction of urban multi-system multilevel traffic,the environmental factors to be considered for the design of the bearing platform foundation pit in the construction process of the upper traffic system are relatively complex,and the boundary conditions are relatively strict.Based on the bearing platform foundation pit project of a highway reconstruction project in Shanghai,this paper introduces the reasonable foundation pit support design scheme to solve the problems of displacement and settlement control in the existing highway and surface road during foundation pit excavation,so as to ensure the safety of road traffic.
