| 摘 要： | 岩土介质的强度参数特别是互相关性分析是岩土工程界研究的热点。本文在分析互相关性的估计和分布检验方法后，通过随机空间正交变换将具有互相关性的ｃ、变换得到独立随机变量，基于Ｍｏｈｒ－ｃｏｕｌｕｍｂ准则，详尽分析了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。

| Abstract: | The correlative analysis of rock-soil strength parameters , especially that of is one the hot points for geotechnical engineering. In this paper , after analyzing the estimation of correlativity of and the method of distribu- tion testing , through the orthonormal transformation in random space , the correlative were transformed and the inde- pendentrandom variables were obtained . Based on the Mohr-coulumb's law , the susceptibility of correlatively of c. tothe reliability of the law was analyzed in detail, and some conclusions of importance to the ieliability desingn in engi- neering were drawn, |
