摘要
季节性的降雨及其所引起的地下水状态变化是促使日本鹿儿岛竜ヶ水地区崩塌、泥石流和滑坡等灾害发生的重要诱发原因。研究地区年降水量达2000mm左右,地下水的影响造成多次崩塌和泥石流的发生,对周围公路和铁路造成极大的危害。鉴于该地区灾害发生与其地质和地下水活动有着紧密的联系,根据多年的降水及钻孔水位的观测资料,建立该地区地下水位模拟的tank模型,并对模型参数进行求解和应用对比分析,为监测预警提供了有力的数据支持。
The seasonal rainfall and corresponding variations of groundwater status due to rainfall are important factors that can induce collapse, debris flow and landslide hazards at Ryukemitsu area, Kakoshima, Japan. The average annual precipitation is around 2 000 mm in the study area; and several collapse and debris hazards occurred due to the influence of groundwater, making a great damage to the surrounding roads and railways. Based on many years of observation data of rainfall and water level, the tank model of the study area has been established to provide a powerful data support for the monitoring and early warning systems.
