| Abstract: | In this paper a random field model of deformation modulus of soil is established by considering spatial variability of soil proper- ties, and variance reduction function in vertical and radial directions is also given, then the effect of vertical and radical self-correlation distances on pile-settlement is studied and some useful results are obtained. |
