摘要
本文根据平稳的和各态历经的随机过程的基本概念及大量钻孔资料，提出了静力触探数据空间分布的平稳性和各态历经性检验的必要性及检验方法；讨论了相关函数形式的选择；通过大量计算比较了求解相关距离的各种方法；分析了相关距离这个概念的工程应用。
Based on the fundamental conception on stationary and ergodic stochastic process and lots of bore hole da-ta,the necessity and method to examine the stationarity and ergodicity of spatial distribution on static sounding testdata was presented. The correlation function was simulated with different mathematical functions. Different ways toobtain correlation distance was compared by large amount of calculation.And the engineering use of correlation dis-tance was discussed.
