| 摘 要： | 滑坡是池州最严重的地质灾害.滑坡的形成除与地质条件有关外,降水和人类工程活动是很重要的诱发因素.通过分析大量的滑坡资料和气象(雨量)数据,研究和探讨了滑坡的发生与降水特征之间的关系,发现滑坡的发生与近3天内的降水强度、过程降水总雨量、降水的持续时间等关系十分密切.结合国内邻近省区的分析结论,建立了一个用日综合雨量预测滑坡的数学统计模型,并对池州1995、1998、1999年3次滑坡等重大突发性地质灾害过程进行了检验,效果良好.

| Abstract: | Landslide is the most serious geo-hazard in Chizhou City.Apart from geological factors,weather and human activity are all quite important causes of landslides.After analysing a great deal of data on landslide and weather(rainfall),we discussed the relationship between landslides and rainfall characteristics and found that a landslide is closely related to the rainfall intensity,total amount of process rainfall and the lasting time of rainfall in the recent 3 days.In consideration of the analytical conclusions from neighbouring provinces at home,we made a statistic model for forecasting landslide with daily synthetic rainfall.The model has been proved efficient for three large-scale landslides in Chizhou in 1995,1998 and 1999. |
