摘要
季节性的降雨及其所引起的地下水状态的变化是促使日本大型结晶片岩滑坡活动和诱发灾害发生的重要原因。基于对一典型结晶片岩滑坡、降雨和地下水位的长期观测,利用Tank模型建立了一种模拟滑坡地下水位变化的方法。通过对滑体内不同观测点地下水位实际观测数据与模拟结果的对比分析,证明所采用的模拟方法能够很好地再现地下水位随降雨的变化形态,从而为预测和评价降雨型滑坡的地下水状态变化提供了依据。
The seasonal rainfall and rainfall-induced variation of groundwater state is the main reason that can provoke the activities of crystalline schist landslide in Japan and even lead to the failure of landslide.Based on the long-term observation data on precipitation and groundwater level at a typical crystalline schist landslide,Zentoku landslide,a method of simulating groundwater level has been proposed by designing a Tank model.By analyzing and comparing the actual groundwater data with the simulated result...
