摘要
为研究上覆第四系覆盖层下伏泥岩类的土-岩复合地铁基坑的变形规律,本文以某地铁某车站深基坑开挖过程为研究对象,开展施工期的围护桩和地表沉降监测,依据ABAQUS数值模拟软件对建立该基坑的数值分析模型并进行了对比分析。
In order to study the deformation law of the foundation pit of the earth rock composite subway with mudstone under the overburden of the quaternary system,this paper takes the excavation process of deep foundation pit of a station of Lanzhou Metro as the research object,and carries out the monitoring of the retaining pile and surface settlement during the construction period.According to the ABAQUS numerical simulation software,the numerical analysis model of the foundation pit was established and compared and analyzed.
