摘要
山西省内山岭重丘区在役高速公路路堤边坡主要以土石边坡为主,经过长期服役后,土石边坡均出现不同程度的病害;为提升在役土石边坡支护处治的精准性,最大程度节约养护成本,以山西省内在役高速公路土石边坡为研究对象,在深入分析边坡病害类型及常用支护处治方法优缺点的基础上,构建了具体的评价指标体系;同时基于均方差决策理论,对不同支护处治方法分类进行了量化比选,并给出了各类处治方法中的最佳方案。
The slopes of Shanxi's in-service expressways in mountainous and hilly areas are mainly the soil rock slopes,and after a long-term service life,the soil rock slopes have different degrees of diseases.To improve the accuracy of the support treatment for the in-service soil rock slope and save the maintenance cost to the greatest extent,this paper established a specific evaluation index system for the soil rock slopes of Shanxi's in-service expressways based on deeply analyzing the slope disease types and advantages and disadvantages of commonly used support treatment methods.According to the mean square error theory,quantitative comparison and selection were conducted for different support treatment classifications,and the optimum scheme was proposed from various treatment methods.
