摘　　要：文章以国道319线黔江段山区公路路基垮塌应急处治工程为例,对衡重式挡土墙用于处治山区公路路基病害进行了应用研究。处治工程竣工后投入使用已近3 a,期间经历了2007年重庆百年一遇的降雨和2008年汶川特大地震,工程完好无损,表明处治工程措施科学合理,工程效果良好。Based on a reinforcing subgrade project in Qianjiang area along national highway 319. the feasibility of using the weighing retaining wall to reinforce the subgrade of highways in mountain areas is analyzed. The reinforcing work had been finished about three years ago. During the period since the reinforcing work finished, the engineering was subjected to the most intensive rainfall in 2007 and the extraordinarily serious Wenchuan earthquake in 2008. No any damage was found in the reinforced work by now, such that the reinforcing method using weighing retaining wall is useful and rational.
