| 摘 要： | 降雨是滑坡灾害的重要诱发因素之一。通过详细的地质灾害调查及地质灾害与降雨相关关系的研究,得出降雨对雅安雨城区地质灾害诱发作用的规律并进一步定量评价了诱发因素级别。研究发现,降雨量对滑坡的诱发因素可划分为4级,1d降雨量分级临界值分别为20mm、50mm和100mm,3d降雨量分级临界值分别为100mm、150mm和240mm。这一研究成果为雅安雨城区地质灾害预警预报提供了基础。

| Abstract: | Rainfall is one of the most important influence factors to regional landslide.The triggering rule can be understood by investigating the landslides and studying the statistics of the relationship between landslide and precipitation.Taking Yucheng District,Yaan City,Sichuan Province as an example region,we evaluated the rainfall triggering factors to landslide quantificationally,and found that the grade threshold values of 1 day rainfall are 20mm,50mm and 100mm and those of 3 days rainfall are 100mm,150mm and 240mm,which is the basis of integrated warning system. |
