复杂工况下三维地基极限承载力可靠度研究之二——地基极限承载力可靠度研究

Research on Reliability of Ultimate Bearing Capacity of Three-dimensional Rectangular Foundations under Complicated Loading Conditions

基于极限分析法上限原理推导的三维解析解,应用可靠度理论,通过与已有的规范公式进行对比与验证分析,其研究成果与第一部分中的研究成果具有较高的一致性,起到了相互验证的作用,表明可靠度设计法在岩土工程设计中具有重要的应用价值与前景。

On basis of the three-dimensional analytical solution deducted by means of the upper bound principle of the limit analysis method, the article makes comparisons with the existing formulas specified in the relevant standards and makes relevant verification analysis by means of reliability theory. The research results of this article coincide well with those of the article published in the last issue of the magazine and they verify each other. The above achievements demonstrate that the design method based on the reliability theory has great practical significance and splendid prospects in the design of geotechnical works.
