岩土介质强度参数相关性的敏感度分析

 岩土介质的强度参数特别是C,Φ互相关性分析一直是岩土工程界研究的热点。本文在分析C,Φ互相关性和分布检验方法后,通过随机空间正交变换将具有互相关性的C,Φ变换得到独立随机变量,基于Mohr-Coulumb准则,详尽分析了C,Φ互相关性对准则可靠度的敏感度。并得出一些对工程可靠度设计有重要意义的结论。

Analyses of Susceptibility in the Strength Parameters Interrelationship of Rock and Soil Media

The analyses of strength parameters interrelationship of rock and soil media,especially those of C and ,have always been the study focus in the field of geotechanical engineering. After analyzing the interrelationship between C and and distributive methods changing the random spatial orthogonal transformation of the interrelated C and ,this paper has got their independent random variables. Based on the Mohrcoulumb criteria, this paper also analyses in detail the susceptibility of interrelationship C and between to the reliability of the criteria. As a result, some significant conclusious for the reliability of engineering designs have been gained in this paper.
