摘要
四川省都江堰市红梅村受2010年8月13日特大暴雨影响,滑坡变形破坏非常严重。通过斜坡变形体的变形迹象分析,在地震、连续降雨或暴雨状况下,将对斜坡产生较大影响。通过对不稳定斜坡采用极限平衡理论传递系数法做出评价,并根据分析结果,提出了以抗滑桩加挡土墙支挡和地表排水相结合的治理措施。治理工程完工后,斜坡土体稳定,外观优美,治理效果较好。
Hongmei Village in Dujiangyan City of Sichuan Province suffered from extraordinary rainstorms on August 13, 2010, which caused serious landslide deformation and failure. The analysis of the deformation sign of the deformed slope indicates that the slope should be affected significantly in the case of earthquake, continuous rainfall or heavy rain. The authors used the theory of limit equilibrium transfer coefficient method to evaluate the unstable slope and proposed the control measures to stabilize the slope by driving friction piles, building retaining walls and providing surface drainage based on the analysis results. After implementation of the control measures the slope becomes stable, pleasing to eye and very effective.
