多年冻土地区单桩横向承载力分析

Analysis on Transverse Bearing Capacity of Single Pile in Permafrost Region

以大型有限元分析软件ANSYS为平台,建立桩-冻土体相互作用的有限元模型,结合工程实例对多年冻土地区灌注桩基础在横向荷载作用下的位移和应力进行分析,并在此基础上分析桩径、冻土温度对其横向承载力的影响。

Taking the FEM software ANSYS as platform,the finite element model of pile-frozen soil interaction was established.The displacement and stress of bored pile foundation under transverse load in permafrost area were analyzed combining with engineering cases.Based on this,the effect of pile diameter and permafrost temperature on the transverse bearing capacity was also studied.
