Abstract

The correlation between the number of landslides and collapses and the rainfall in Longsheng county was analyzed. It was found that there were 2 inflection points in the correlation graph between the quantity of geological disasters and the rainfall. The rainfalls corresponding to the inflection points were critical rainfalls indicating abrupt changes in the number of rainfall-induced landslides and collapses. Based on these critical rainfalls, rainfall periods corresponded to high, middle and low risk grades of geological hazards in the county were divided. In order to predict the risk of geological disasters, the county is divided into different geological disaster prone areas according to disasters frequency. During disaster forcasting, the predicted daily rainfall or 3 days cumulative rainfall are first collected and checked what the rainfall period it will belong to, then a corresponding forecast chart of geological hazards is adopted to predict the risk of geological hazards in the whole county.
