苍梧县城区防洪堤抗滑桩非线性有限元分析

Non-linear finite element analysis of anti-slide pile for flood dike in Changwu county

苍梧县城区防洪堤主要地段采用钢筋砼箱式堤型、人工挖孔桩基础的设计方案。应用ANSYS有限元分析软件,对桩与土的相互作用进行有限元分析,计算内桩、外桩出现的最大拉应力、弯矩、剪应力及其出现的时间,从而判定防洪堤的稳定性。

The major sections of flood dike in Changwu county are of reinforcement concrete box structure designed with artificial digging pile foundation. ANSYS software is applied in finite element analysis of interaction between pile and earth, including the calculation of the maximum tensile stress, bending moment, shear stress of inner piles and outer piles as well as the occurrence time, which will help us estimate the stability of flood dike.
