土的抗剪强度指标的随机场统计方法

When applying random field theory to reliability analysis, one of the most important problems is how to consider the auto correlation and cross correlation of the shear strength of soils. In this paper, the stochastic statistical methods for characteristics of shear strength are presented based on the traditional statistical methods. Both the auto correlation of the individual index and the cross correlation between the indexes can be considered when using the stochastic statistical methods. It is proved that the methods can make the reliability analysis more reasonable and convenient by calculating an example of engineering.
