摘要
为提高赣南地区地质灾害降雨量监测预警设备的有效性,以赣南地区120处有代表性的地质灾害历史事件为研究对象,观测和记录,建立累积降雨量、降雨强度和降雨历时三者之间关系模型,拟合出不同地层地质灾害发生时临界降雨量阈值-降雨历时曲线和经验公式,可为该地区地质灾害监测、预警和防治提供借鉴和依据。
In order to improve the effectiveness of geological disaster rainfall monitoring and warning equipment in South of Jiangxi Province,120 representative geological disaster historical events in the region were taken as the research object,and a relationship model between cumulative rainfall,rainfall intensity,and rainfall duration was established through observation and recording.The critical rainfall threshold-rainfall duration curve and empirical formula for geological disaster occurrence in different strata were fitted,which can be used for geological disaster monitoring in the region,and provide reference and basis for early warning and prevention.
