摘　　要：为掌握镇江地区地基土的随机特性,本文基于随机场理论和镇江地区不同地层年代、沉积环境和岩土类型的土层静力触探试验数据,计算得出不同土层的竖直向相关距离和水平向相关距离的代表值和变异系数,对比递推空间法与求解新方法等不同方法的计算结果,并分析得出土性参数空间变异性和土层均匀性是影响相关距离值的主要因素。In order to grasp the random characteristics of the foundation soil in Zhenjiang area,based on the random field theory and the static cone penetration test data of different strata age,sedimentary environment and geotechnical types in Zhenjiang area,the representative values and variation coefficients of the vertical and horizontal correlation distances of different soil layers are calculated,and the calculation results of different methods such as the recursive space method and the new method are compared.The results show that the spatial variability and soil layer uniformity are the main factors affecting the correlation distance.

关 键 词：镇江地区 土性参数 随机场 相关性 空间变异性 相关距离
