摘要
文章研究了一种既有地铁车站盾构洞门改造为矿山法洞门的设计与施工方法,并采用Autodesk Robot Structural Analysis Professional软件,建立三维有限元模型,模拟将车站端墙预留的盾构洞门改造为矿山法洞门后,对既有车站端墙产生的影响,同时将数值模拟结果与现场监测数据进行了比较,显示计算结果与实际情况较为吻合.
Abstract
This paper studies the design and construction method of transforming the shield tunnel portal into the mine tunneling method tunnel portal in the existing subway station,and uses Autodesk Robot Structural Analysis Professional software to establish a three-dimensional finite element model to simulate the influence of transforming the shield tunnel portal reserved for the end wall of the station into the mine tunneling method tunnel portal on the end wall of the existing station.At the same time,the numerical simulation results are compared with the field monitoring data,which shows that the calculation results are in good agreement with the actual situation.
