以某深基坑工程为研究对象,利用有限元分析软件ABAQUS建立了考虑临近建筑物荷载影响的二维数值模型,模拟开挖实际工况。对土体开挖引起的土体塑形应变及基坑的稳定性进行分析计算,对建筑物位置及基础埋深对基坑稳定性的影响进行探讨。计算结果可为工程设计与施工提供理论依据,也可为类似工程提供参考。
Taking a deep foundation pit project as the research object, a two-dimensional numerical model considering the influence of the load of adjacent buildings was established by finite element analysis software ABAQUS to simulate the actual working conditions of excavation. The deformation of soil and the stability of foundation pit caused by soil excavation are analyzed and calculated, and the influence of building location and foundation depth on the stability of foundation pit is discussed. The calculation results can provide theoretical basis for engineering design and construction, and also provide reference for similar projects.
