| 摘 要： | 在建筑地基基础设计中,地基承载力的确定是一个重要的问题,尤其地基承载力的可靠度分析则更是一个新的课题.本文提出了一种地基承载力可靠度分析模式,并对影响地基承载力可靠度指标的各因素进行了分析;还提出了根据地基土抗剪强度指标的变异性(或统计参数)确定可靠域分析的概念,从而对在工程实践中确定地基承载力的可靠性提供了一种方便适用的方法.

| Abstract: | It is an important step to determine the bearing capacity of foundation in a design.It is a challenge to do the task of the reliability analysis of bearing capacity.A mode of the reliability analysis for the bearing capacity of foundation is proposed in the paper.The reliable index is used to illustrate the degree of reliability.We discuss the factors effected on the reliable index.A new idea to ascertain the reliability zone is provided.It depends on the variation of a shear strength of soil.At last,a new way to determine the reliability of foundation is provided by the means of the proposed mode. |
