| 摘 要： | 简要介绍了Kriging方法的基本原理及变异函数的模拟, 并从三维结构模型的体元离散、实验数据搜集与探究、空间变异结构分析以及插值方法应用等方面详细阐述承载力三维实体建模的基本思路。提出以三维地质实体建模技术同Kriging方法相结合的策略分析并模拟天然地基土承载力的空间分布规律, 并以三维可视化技术对其进行刻画和表达。以北京某区域为例, 利用该区887个实验样品数据, 采用Kriging插值与三维实体模型结合的方法, 构建了研究区承载力三维实体模型, 并将模拟结果与传统二维Kriging方法建模结果进行了对比分析。结果表明, Kriging插值与三维实体模型结合的方法不但精度高, 而且直观、准确的三维可视化表现方式为专家的决策提供了便利。
