摘要:
依托黄土地区某城市地铁车站深基坑工程为背景,建立有限元模型,对深基坑施工过程进行有限元分析,对不同工序下深基坑围护结构的变形规律进行研究;以土层粘聚力、钢支撑位置及桩入土深度为影响因素,分别进行模拟分析。研究表明:有限元模拟方法能有效反映基坑维护结构位移变形规律,黄土粘聚力、钢支撑施作位置及围护桩入土深度的变化对基坑围护结构及周围地表位移有一定影响,设计中的钢支撑位置是最优的设置位置。
Abstract:
Taking the deep foundation pit of the subway station in some city of the loess area as background,a finite element model was established,and the analysis on the construction process of the deep foundation pit was conducted,then the deformation law of the deep foundation pit palisade structure in different processes.Taking soil strength,steel strut position and pile depth in soil as influencing factors,they were simulated and analyzed respectively.Research showed that : the finite element simulation method could effectively reflect maintenance structure displacement deformation law of foundation pit,the change of loess sticky gathered force,steel strut position of pile and retaining pile’s depth in soil had certain influence on pit supporting structure and surface displacement around,the steel strut position was optimal position setting in the design.
