摘　　要：在某磷矿采场边坡岩体工程稳定性分析中,为了获得力学参数的准确值,利用各种随机模拟技术对概化出来的节理统计模型进行再现,并通过大量抽样,模拟数值"加载试验",并对"试验"结果进行统计分析,分析表明最后得到岩体变形强度参数的估算值符合工程实际.为今后的工程实践中获得岩体力学参数提供了一条切实可行的方法.To estimate the rock＇ s REV as well as distortion and strength parameters, based on a practical project, the joint statistics model was reconstructed using various random simulation skills, and numerical simulation on loading test was conducted. The research results show that the estimation of deformation and strength parameters accords with the practical project, which verifies the feasibility of the method.
