【摘要】 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。更多还原

【Abstract】 Research has been done on the vertical displacement of pillars in super-deep pit foundation based on the establishment of finite element model under the use of software ABAQUS.Through the comparison of the simulation results and monitoring data,it could be indicated that the model established to simulate the excavation of pit foudation is feasible.The vertical displacement of pillars and its impact on flat-slab stresses and displacement were studied.The degree of influence of various factors which effect the vertical displacement of pillars was discussed.更多还原
