摘　　要：以重庆市江北城变电站至五里店站电缆隧道下穿对山立交桥梁工程为背景,利用有限元软件Midas-GTS模拟电缆隧道开挖过程,分析电缆隧道开挖对市政桥梁工程运营的安全性和可行性,并提出电缆隧道施工中应该注意的问题,其对以后类似工程具有良好的参考价值和指导意义。With cable tunnel underneath mountain interchange bridge project from Jiangbeicheng Substation to Wulidian Substation of Chongqing as background, this paper simulates excavation process of cable tunnels by means of finite element software Midas-GTS, analyzes safety and feasibility of excavation of cable tunnels to operation of municipal bridge project, and proposes the problems those should be noticed in construction of cable tunnels. Numerical simulation in the paper exhibits perfect reference value and guiding significance for similar projects in the future.
