摘要
考虑土体参数的空间变异性，建立了上体变形模量的随机场模型并推导了方差折减系数计算公式，研究了竖向和径向自相关距离对桩体沉降变异性的影响。
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.
