Analysis of the Impact of a Certain Project in Changchun on Ground Settlement Caused by Foundation Pit Dewatering
This article takes an actual foundation pit project in Changchun as the background,and simulates the precipitation situation inside the foundation pit using Midas GTS NX software.The influence of the precipitation stage of construction on the surrounding surface environment and support structure deformation is obtained.The results indicate that the settlement effect caused by the precipitation process on the surrounding surface is centered around the precipitation well,forming a precipitation funnel shaped curve.The maximum settlement value occurs near the precipitation well,and the maximum deformation effect on the support structure occurs at the top of the pile.As the depth of the pile decreases,it shows a downward curve.Layered precipitation can play a good role in controlling surface settlement.
