摘要:
针对目前单一判据评判公路边坡稳定性状态存在种种不足的现状，分析了公路边坡地质灾害发生的特点和影响边坡安全的主要因素，提出了安全模糊综合预警方法.运用案例统计回归分析法、数值模拟分析法和边坡围岩蠕变理论，分别确定公路边坡稳定极限状态的累计位移阈值、降雨量阈值、变形速率阈值与变形加速度阈值.在此基础之上，运用专家评分法确定各判据的权重，构建判断矩阵，经模糊逻辑推理判明边坡稳定性状态，从而实现安全预警.利用所建预警模型分析边坡近两年的监测数据，进行了两次预警，其最危险结果均达到Ⅲ级.结果表明：预警结果与实际情况完全吻合，在该工程中取得了良好的效果，很好的弥补单一判据的局限性.
Abstract:
Aimed at the limitation of single criterion to judge the highway slope stability,fuzzy comprehensive earlywarning method was put forward.Based on analyzing the characteristics of highway slope geological disaster and the main factors affecting the safety of slope,the thresholds of cumulative displacement,the rainfall amount,deformation rate and acceleration were determined using the statistical regression analysis,the numerical simulation and the characteristic of rock creep.Experts grading method was used to determine each criterion weight values.Consequently,the judgment matrix was formed.Finally the safety earlywarning was carried out through fuzzy logic inference to judge the state of slope stability.Two earlywarnings were conducted using the presented earlywarning model in one slope,and the most dangerous result achieves Ⅲ level with the observed data in recent two years.The results show that the earlywarning results are consistent with the actual situation,and they make up for the limitations of a single criterion.
