摘要
随着我国工程建设项目的广度和深度的推进,新建与既有工程相互干扰的范围越来越广。借助一临近高铁既有隧道民用工程的建设,采用Midas GTS分析软件,建立三维数值模型,模拟新建建筑物基坑开挖、主体结构附加荷载对下设既有隧道的影响。希望通过此次计算分析,确保高铁运营线安全,同时为同类工程建设项目提供参考。
With the development of the breadth and depth of construction projects in China,the scope of mutual interference between new and existing projects is becoming wider and wider.In this paper,with the help of the civil engineering construction of an existing tunnel adjacent to the high-speed railway.Using Midas GTS analysis softwar,building a three-dimensional numerical model,simulate the influence of foundation pit excavation of new building and additional load of main structure on existing tunnel.It is hoped that this calculation and analysis can ensure the safety of high-speed railway operation line and provide reference for similar engineering construction projects.
