摘　　要：鉴于散粒堆积体滑塌风险评价尚处于经验研究阶段,针对风险评价定量化不足的现状,提出一种针对散粒堆积体滑塌影响区域概率分布的思路。即在大量重复模型试验的基础上,得出试验堆积体在试验地坪上覆盖区域的等值线图,模拟滑塌影响区域的概率分布,进而划分堆积体滑塌时的危险安全区域,为人类生产生活用地选址提供了参考。The research on the risk assessment of the bulk accumulation body sliding is a late starting in China,which is still in the stage of empirical research.For this purpose,a new method is proposed to evaluate the probability distribution of the bulk accumulation body in the area of the risk assessment.Based on a large number of repeated tests,the model tests are used to get the contour map of the area covered by the test pile,and the probability distribution of the sliding zone is simulated.Furthermore,the hazardous and safety zone of accumulation body sliding was divided.So,it provides reference for site selection of production and living land use.
