摘要

运用系统可靠度理论，根据柔性桩复合地基分别按承载力设计和变形控制设计的不同计算方法，将复合地基整体系统分为复合地基承载力子系统、变形子系统、差异变形子系统，分别进行可靠性分析，并计算整体系统失效概率。提出了复合地基的系统可靠性分析方法，为复合地基的优化设计提供了一种思路。

Abstract

Based on bearing capacity and settlement control design methods for composite foundation improved by flexible piles

as well as the system reliability analysis theory

the system of reliability analysis for composite foundation can be divided into three sub-systems; that are bearing capacity sub-system

settlement sub-system and settlement difference sub-system. The system probability of failure for composite foundation can be obtained by calculating that of three sub-systems respectively. It provides a method of system reliability analysis for composite foundations.
