摘要
在可靠性理论的基础上,建立了高速公路台背处水泥搅拌桩复合地基沉降的权限状态方程,给出用 JC 法(当量正态化)求复合地基沉降的随机可靠度的方法,并结合工程实例用 MATLAB 编制程序进行辅助计算,求出其在容许沉隆量下的失效概率,为控制桥头跳车提供理论依据。
Based on the theory of reliability, the limit state equation was established for the settlement of cement mixed pile under the abutment of the freeway, a random reliability analysis for the settlement of the compound foundation used JC method was presented,with a practical example and the MATLAB program composition,we can get the failure probability within the permissible settlement quantity, this can provide a theoretical basis for the control of bridgehead-bump in project.
