基于Monte-Carlo的弃渣场可靠度分析OA
Reliability Analysis of a Waste Disposal Site Based on the Monte Carlo Method
弃渣在堆积过程中由于其颗粒大小不均匀,致使其不同部位取样测得的参数值具有空间差异性.为研究降雨对紫阳县一处弃渣场稳定性的影响,在现场勘查及取样试验的基础上考虑弃渣在堆积过程中内摩擦角和粘聚力的随机性,并借助Geo-Studio软件对边坡在不同降雨条件下的稳定性进行可靠度分析.得出不同条件下该边坡失效的概率及稳定系数,以此来弥补单纯数值计算的缺陷,提高边坡稳定性预测的准确性,可为该弃渣场后续治理工程提供一定的参考依据.
Due to the heterogeneous particle size distribution of waste materials during accumulation,geotechnical parameters obtained from different sampling locations exhibit significant spatial variability.To investigate the impact of rainfall on the stability of a waste disposal slope in Ziyang County,field investigations and laboratory tests were conducted,and the randomness of internal friction angle and cohesion was considered.Reliability analysis under different rainfall conditions was performed using Geo-Studio software combined with the Monte Carlo method.The failure probability and safety factor of the slope under various conditions were obtained.This probabilistic approach compensates for the limitations of traditional deterministic numerical calculations and enhances the accuracy of slope stability prediction,providing a technical reference for subsequent remediation of the waste disposal site.
