摘　　要：本文以某深基坑工程为依托,基于土拱理论和土压力等监测数据分析在基坑施工开挖施工过程中坑角效应对基坑土体和周边建筑物的影响。研究结果表明:在同一深度处,内部支撑对阳角处围护结构下部的抑制作用不明显,同一施工工况下凸出长度越大,基底隆起量越大。Based on the foundation pit project of Shenyang north railway station comprehensive traffic junction reconstruction and expansion project,this paper analyzes the influence of uneven settlement caused by pit Angle effect on buildings based on soil arch effect theory and soil pressure monitoring data.The deformation characteristics of buildings at the corner of pit under the influence of foundation pit excavation were studied.
