Analysis of Superposition Influence of Adjacent Excavation on Peripheral Settlement
In order to analyze the influence of multi-foundation pit excavation on surrounding settlement,Midas GTS software was used to es-tablish a model to simulate and analyze the evolution law of surrounding buildings and surface settlement during the process of foundation pit ex-cavation and dewatering.The results show that when the foundation pit is excavated alone or dewatering,the settlement of the surrounding buildings increases linearly with the distance from the foundation pit.When the adjacent foundation pit is constructed at the same time,the curve of the surrounding settlement and the distance from the foundation pit is parabolic.When the excavation or dewatering of adjacent founda-tion pits is combined,there is a superposition effect on the settlement measure of surrounding buildings.The closer to the foundation pit project and the deeper the precipitation depth,the greater the surrounding surface settlement.
