【摘要】 针对岩土剪切强度参数粘聚力与内摩擦角之间具有相关性的特点 ,引入广义随机空间概念 ,推导出广义随机空间内地基承载力可靠度分析的计算公式 ,并编制成应用程序 ,对某工程的地基承载力可靠度进行分析 ,结果说明在岩土工程可靠度分析中 ,随机变量之间的相关性对可靠度分析的结果影响很大 ,必须予以考虑。更多还原

【Abstract】 By introducing generalized random space conception to deal with the relativity of shear strength variables of rock or soil, the calculation formulas of foundation bearing capacity reliability analysis in generalized random space were deduced and the program was worked out. The reliability of one project’s foundation bearing capacity was analyzed. The results proved that the relativity of random variables affect reliability analysis result and must be considered.更多还原
