易滑超倾坡水力启动滑移破坏的现场模拟试验
Site simulation test on easily slip over dip slope bedding-slip failure caused by groundwater pressure
摘要
Abstract
The stability of easily slip over dip slope is mainly affected by groundwater pressures on the slope rock mass. It was simulated on site that the bedding-slip failure test caused by groundwater pressure in easily slip over dip slope. The test verified water through rate at the potential sliding plane, which must consider in rock slope stability analysis of groundwater effect. The correctness of the basic mechanical model of the easily slip over dip slope was verified. It was also tested that the front of landslide was starting early and had the phenomenon of water seepage or water sprinkling in front of landslide body before landslide occurrence. The test results showed that when the groundwater pressures suffered by potential sliding plane rise to the sliding threshold, the huge landslide occurred. Finally, it was proposed that the reliable methods of monitoring groundwater pressures threshold suffered by the front of potential sliding plane.关键词
