土性指标的变异特性研究

Study of Variable Behavior of Soil Index

本研究以实际工程的勘察测试资料为依据 ,采用概率统计与随机过程理论 ,分析计算了地基土抗剪强度指标 c、和静力触探比贯入阻力 ps等土性指标的均值、变异系数和相关距离等概率特征值 ,既是对土性指标本身的一种深入的探索 。

On the basis of field investigation and test data,the probabilistic characteristic values such as the average value,variable coefficient,relative distance of the shear strength index, c,φ ,and specific penetration resistance p s of static penetration tests of soil are analyzed and calculated with the probability statistics and random process theory.The study is not only a deeper exploration into the soil index itself,but also provides necessary technical parameters for the reliability analysis of geotechnical engineering and the determination of partial factors in foundation designs.
