摘要
以某异形基坑工程为研究对象,采用FLAC3D有限差分法对其开挖和支撑过程进行数值模拟,得到SMW工法桩体水平位移和钢支撑轴力的变化规律,并将结果与类似封闭基坑数值模拟计算结果进行对比分析,最终得出异形基坑施工的变形特性。
This paper takes a deformed pit as the study subject,using finite difference method of FLAC3D model to make numerical simulation to the processes of excavation and support.The changing rules of SMW pile horizontal displacement and steel-supporting axial force.The results are compared and analyzed with the numerical simulation algorithm results to similar closed pits.Finally the characteristic of deformation during the construction of deformed pit are achieved.
