摘　　要：通过大量的试验来分析和了解岩土力学参数的空间变异特征,找出人工压实填土的物理力学性质指标之间的相互关系,来判断人工压实填土的施工质量,掌握高填方土体的变化规律.从而为预测和判断高填方土体将来边坡的局部稳定和整体稳定提供设计参数,为优化设计方案和优化全场高填方的稳定性治理措施提供依据.The spatial variance characteristics of geomechanical parameters are analyzed through many experiments in this paper. The relationship between the physical mechanical indexes of the artificial fill is pointed out for the purpose of judging the construction quality of artificial fill as well as mastering the changing rules of high fill soil. Designing parameters are thus provided to forecast and judge the partial as well as overall stability of high fill soil, which serves as a basis for the stability treatment measures to optimise the design scheme and high fill soil.

关 键 词：抗剪强度 边坡稳定 岩土力学
