摘要

根据随机场理论，对求解土层相关距离的递推空间法和相关函数法进行比较和探讨，指出两种方法所求得的相关距离值存在偏差的原因，并从理论上证明当样本容量足够大时两种方法的计算结果可以得到统一。对相关函数法作出改进，使其更易于曲线的拟合和参数的确定，最后采用实际工程的勘察测试资料进行了分析计算，验证了由计算公式推导所得的结论在实际工程中也是成立的。

Abstract

The two different methods for estimating the correlation distance of soil layers are compared and studied based on the random field theory. The reason why difference correlation distances may be estimated by different methods is explained. The results obtained by using both methods respectively are proved to be approximately the same if the number of samples is large enough. The correlation function method is improved in order to make the curve fitting and parameters determination easily. The conclusion is validated through calculation of some investigation data of practical engineering.
