摘要
Abstract
This article combines real-time monitoring data of a foundation pit to analyze the changes in foundation pit performance during foun-dation pit excavation.The results show that during the excavation of the foundation pit,the axial force of the support,the lateral displacement of the retaining structure and the support force of the column all increase significantly,and tend to stabilize after the excavation of the pit bot-tom;the maximum lateral displacement of the support structure The lateral displacement increases with the increase of excavation depth;the lateral displacement of the supporting structure and adjacent pipelines is smaller at the corner of the foundation pit and larger at the center of the foundation pit wall;the ground settlement around the foundation pit increases first,and then It decreases in the direction away from the wall;finally,the calculation method of soil settlement is corrected by introducing a stiffness correction function to more accurately predict the settlement of the pipeline.关键词
