| 摘 要： | 通过建立承载力计算的极限状态方程,结合工程实例,运用可靠度理论,对两阶段变刚度桩筏基础的承载力进行了可靠度分析与验证,对其安全系数指标和可靠度指标的关系进行了研究分析,得到了基于概率极限状态设计方法即现行规范《建筑结构可靠度设计统一标准》的可靠度指标,验证了采用安全系数法作为两阶段变刚度桩筏基础承载力验(计)算方法的合理性。

| Abstract: | In this paper the reliability for the bearing capacity of the two phases varying stiffness pile-raft foundation was analyzed by means of the establishment of limit state formula.The relationship between the safety and reliability was studied in details.The reliability index based on the probability limit state design method was obtained.It was verified that using the safety coefficient method as a computing method for the two phases varying stiffness pile-raft foundation is reasonable.This research is with great value to the pile foundation design for buildings. |
