摘要
根据Vanmarcke提出的随机场理论描述土性参数的空间变异性,并通过实例采用改进的Monte＿carlo方法计算地基承载力可靠性指标,在该过程中考虑土性参数的空间变异性以及土性参数间的互相关性,将计算结果与直接Monte＿carlo法及JC法进行了比较,得出了一些有价值的结论.
This paper applies the theory of random field proposed by Vanmarcke to describe the spatial variability of soil properties. The modified Monte_carlo method is used to calculate the reliability index of foundation bearing capacity by means of an example. In this process, the spatial variability and cross_correlation of soil properties are considered. The results are compared with those of the direct Monte_carlo method and JC method, and some useful conclusions are drawn.
