摘要
为研究地铁区间浅埋暗挖隧道施工对地面建筑物的影响,结合A校实际工程建立的6层框架建筑-双线轨道的PIC模型,分析区间隧道开挖作业对地面建筑物的影响,结果表明:利用PIC法得到的建筑物沉降量规律符合工程实际情况;A校建筑物产生的倾斜变形不超过地基规范允许的最大变形;地表建筑物的沉降量随着与开挖隧道的距离的增大而增大,并且以隧道轴线成正态分布.
Combined with the 6-story frame-double track PIC model established by School A,this paper analyzes the influence of subway interval shallow tunneling on ground buildings' safety.The result shows the sedimentation amount of the building conforms to the actual situation of the project,the inclined deformation of the building does not exceed the allowed maximum,and the sedimentation amount of the ground buildings increases with the increase of the tunneling distance and the tunnel axis is at normal distribution.
