Study on rainfall thresholds for mud slides and landslides in Guangxi
摘要
Abstract
Based on the geologic hazard events and its corresponding hourly precipitation data from 2012to 2016, this paper used statistical method to analyze the rainfall threshold for mud slides and sand landslides in Guangxi and used the disaster happened in 2017 to test and revise the rainfall thresholds.The results showed that antecedent rainfall played a leading role in debris flow and landslide in Guangxi.When 24h precipitation was less than 152mm, the rainfall threshold for mud slides H1=-0.2872H24+83.55, otherwise the threshold H1 =39.9mm. For landslide, the curve of rainfall last and its density follow the formula I=11.31D-0.7.关键词
