基于 ANSYS 和 JC 法的滑坡抗滑桩结构可靠度分析
Reliability Analysis of Anti-slide Pile Based on JC Method and ANSYS
摘要
Abstract
Based on the in-depth analysis of the geometric meaning of reliability index and the basic theory of JC method,the performance function of anti-slide pile soil system is proposed.On the basis of analysis of engineer-ing geological conditions of Dalugou loess landslide in Wuqi County Shaanxi Province,according to the landslide geological survey data and design information of landslide remediation engineering,the finite element model-based ANSYS software platform of anti-slide pile soil system is established.The numeric simulation results of pile and soil system under own weight condition proves the validity of the finite element model.Moreover,the density γof land-slide,cohesion c and internal friction angle of slide surface,and compression modulus Es,four random variables of sliding bed,the reliability calculation model of anti-slide pile based on ANSYS software and JC method is estab-lished,and the corresponding algorithm is developed.The sample calculation shows that,the probability of failure of anti-slide pile structure Pf=0.49% and β=2.58,which is little larger than that of MCS Sampling method,and that of CCD Responding Surface method.The example verified the validity of the reliability model and correspond-ing algorithm.关键词
