摘要

由于岩土参数具有很大的不确定性，在深基坑抗隆起稳定性分析中高安全系数并不一定安全。为此，提出了深基坑抗隆起稳定性可靠度分析方法，基于Rosenblueth方法开发了相应计算程序，研究了土性参数c，变异性对可靠指标的影响，并通过实例分别运用可靠度和安全系数分析方法分析深基坑抗隆起稳定性。结果表明:可靠度分析方法具有科学性和合理性，同时体现了Rosenblueth方法在复杂功能函数中进行可靠指标计算的优越性。

Abstract

Due to uncertainty geotechnical parameters

the higher security coefficient is not always stable in the analysis of deep excavation against heave stability. Therefore

this paper puts forward a reliability analysis method for deep excavation against heave stability

and develops corresponding computer programs based on the Rosenblueth method to research the influences of soil property parameters c and φ variation on reliability indices. In addition

the paper analyzes by instances deep excavation against heave stability using the reliability analysis method and security coefficient analysis method. The results show that the reliability analysis method is scientific and reasonable; for complex equations

the Rosenblueth method has an advantage over others in calculating reliability indices.
