摘　　要：GIS岩土工程决策评价系统是城市数字化的一个重要组成部分 ,如何充分利用已有的工程勘察信息、评价成果对预测和评价场地工程性状是系统性能效能的重要表征。该文基于地质统计学方法 ,分析了饱和砂土场地液化势数据结构特征 ,并对整个区域进行了空间插值。结果表明Kriging方法适用于砂土场地液化势及其它岩土参数的空间估值。The geotechnical engineering decision and evaluation system is a vital part of digital system of city. The performance of the system can be evaluated based on that the system can whether or not make full use of available reconnaissance information to evaluate a site. The paper analyses structural characteristics of liquefaction potential data of a saturated site and draws the contour of liquefaction potential of the site. The results indicate Kriging method is suited for spatial estimation of liquefaction potential and other geotechnical parameters.
