LANDSLIDE MECHANISM OF A SLOPE IN NANHUAN ROAD, FUNXIN, NORTHEAST CHINA (2017)
Targeted at a slope in Nanhuan Road, Fuxin, Northeast China, this paper explores the cause and failure mechanism of landslide through site survey, surface displacement monitoring, inclinometer measurement, and limit equilibrium analysis. It is concluded that the landslide is mainly attributable to the load increase on slope crest induced by subgrade backfill and the rise in groundwater table resulted from rainfall infiltration. The results of the monitoring and limit equilibrium analysis show that 2 slip surfaces were placed at reasonable positions in the slope. Through the analysis of monitoring results, the mechanism of the landslide is summarized as gradingcreeping-sliding mechanism. Finally, the sliding mass was portioned to lay the basis for further slope management.
