摘要
太原一、二号地铁联络段位于大南门站附近,采用明挖加盾构的施工方法。此联络线曲率大、坡度大,所处位置地质条件复杂敏感,盾构区间下穿迎泽公园。为控制盾构时土体扰动对建筑物的影响,在重点地区布置监测点进行土体和建筑物沉降监测,采用有限元软件ANSYS对该盾构区间部分风险点进行三维建模分析,将所得计算数据与现场监测数据对比分析,得出盾构位置变化对监测点土体以及建筑物沉降的影响。
The connecting section of Taiyuan No.1 and No.2 subway is located near Danan Gate station,and the construction method of open excavation and shield is adopted.This tie line is characterized by large curvature,large slope,complex and sensitive geological conditions.The shield section passes through Yingze Park,and the disturbance of its excavation to the surrounding soil will cause uneven settlement of surface buildings.In order to control the impact of soil disturbance on buildings during shield tunneling,monitoring points were arranged in key areas to monitor the settlement of soil and buildings.At the same time,the research analyzed the three-dimensional modeling of some risk points in the shield tunnel by the finite element software ANSYS,and the calculated data were compared with the monitoring data collected on site to obtain the impact of shield position change on the soil and building settlement at the monitoring point.
