基于大型软件ABAQUS建立有限元模型对超深基坑立柱竖向位移进行研究。通过立柱竖向位移模拟计算结果和实测值的对比,说明所建立的模型模拟基坑开挖具有可行性。研究了立柱竖向位移对水平梁板应力和位移的影响,并讨论了影响立柱竖向位移的各因素及其对立柱竖向位移的影响程度。
Based on the large scale software ABAQUS, the finite element model was established to study the vertical displacement of pillars in ultra deep foundation pit. Through the comparison of vertical calculation results and measured values, it is feasible to simulate the excavation of foundations. The influence of vertical displacement of column on the stress and displacement of horizontal beam is studied. The factors affecting the vertical displacement of column and the degree of influence on the vertical displacement of vertical column are discussed.
