利用人工降雨模拟器模拟了不同历时、不同强度的降雨,对坡积层滑坡体内部的孔隙水压力、土体含水量、地下水位和斜坡表层的地表径流进行长时间序列监测,分析了近饱和坡积层斜坡入渗与地表径流的规律,揭示了监测指标对土体的变形和破坏可能的影响机制。

The artificial rainfall simulator was used to simulate different durations, different rainfall intensities on a colluvial landslide. During the experiment period, the internal pore water pressure, soil moisture, ground-water level and surface runoff were monitored. A time series analysis was conducted based on the monitoring index on the nearly saturated colluvial slope to obtain the infiltration and runoff patterns, and to reveal the influence mechanism of monitoring indicators that affect the deformation and slope failure.
