填方边坡加高失稳原因分析及加固

The cause analysis and reinforcement for the heightening instability of a fill slope

某填方边坡加高后,坡顶产生开裂变形、挡土墙出现鼓出,文章分析了其失败的原因,并根据该边坡工程场地条件、地质条件,因地制宜,采用放坡卸载、坡脚增设重力式挡墙反压加固、设置排水管进行坡体排水等综合治理措施,保证了边坡的稳定性,效果好、施工工期短、工程造价低,产生了良好的经济效益。

After a fill slope was heightened,cracks were generated at the top of the slope,and bulging occurred in the retaining wall. This paper firstly analyzed the failure reason for the former design. Then according to the site and geological conditions of the slope,measures of unloading,building gravity-type retaining at the slope foot,and building drainage pipe for slope drainagewas taken. With those comprehensive measures,the stability of the slope was ensured,andgood economic benefitshave been achieved for its good effect,short construction period and low construction cost.
