摘　　要：该文根据Vanmarcke提出的土层概率模型、土性相关距离的定义及方差折减函数I2（h）的基本性质，在递推空间平均法的基础上，提出了曲线拟合法计算相关距离，并从理论上证明了其方法的合理性。该方法克服了以往计算结果受人为影响较大的不足。In accoedance with soil layer probability Anel, the deftaltion of soil property correlative distance and the fundamenal of the vdriance whction fonction P (h ) suguted by Vche, ed on the mnce space average method, the PaPe ~ts the curve fitting Ineha to calculate the coedative distane, and proves the hoonality of the method on a thedical basis. This method overeon the dinciency of the foor methwh, in which the reSults are greaily influenced by man - made factors.
