Abstract:

A field monitoring program was carried out to record the slope failure process of a landfill with multiple intermediate covering layers. The monitored items include the leachate level, the surface horizontal displacement and the deep lateral displacement. Based on the monitoring data, analysis was carried out to verify the stability control effects of leachate drainage on the top layer, leachate drainage in different layers, and near-slope leachate drainage. The results show that the maximum slip area is 34 760 m² and the average surface horizontal displacement of the 10th platform is 1.77 m. Dumping near the slope is the main reason for the instability. The closer to the dumping area, the greater the degree of slip and the more significantly the leachate level rises. Affected by the intermediate covering layers, the failure mode is the local sliding inside the landfill, and the effect of near-slope leachate drainage on the stability control is obvious.
