临近既有地铁隧道新建基坑的数值计算分析
Nu merical analysis of the influence of the excavation of excavations u pon and beside the existing tu nnel
摘要
Abstract
In this paper,the finite element software was used to conduct the three-dimensional simulation analy-sis for the construction of key protection area in Shenzhen Metro Line 1 1 Chegongmiao station.The excavations are designed upon and beside the No.1 line interval tunnel.Through comparison with measured automatic moni-toring data,the validity of the simulation was verified.By extracting the calculated results of the deformation of tunnel structure caused by construction of air duct,the deformation behavior of existing tunnel structure in this case was understood,and the affected key part of existing tunnels was given.The conclusions will be helpful for proposing the security protection measures in the process of the construction,and can provide beneficial reference for the similar projects in the future.关键词
