复合桩基极限承载力的可靠度分析

Reliability Ananysis of Bearing Capacity of Complex Pile Foundation

运用结构可靠度理论，同时结合一个工程实例，对复合桩基稳定极限状态方程进行了较为全面的可靠分析。并对各抗力基本变量变异系数的敏感性、可靠指标与安全系数的关系、考虑承台分荷效应对复合桩基稳定可靠度的影响等方面作了进一步的探讨。

In this paper the, structural reliability theory is used to analse the reliablity of ultimatestates of complex pile foundation by means of a project example. further research is carried out on suchaspects as sensitivity of basic variables, of every resistant relationship between index of reliability andsafety fortor, influence on index of reliablity by platform which subjects to actions.
