A Study on the relationship between the occurrence of landslides and rainfall
Yucheng Zhang@GuangDong Research Institute of Water Resources and Hydropower Guangzhou China;Haiying Hu@Pearl River Water Resources Scientific Research Guangzhou China Based on the analysis of geological data and meteorological data of landslide, the mechanism of rainfall-induced landslides was analyzed, and the relationship between landslide and rainfall was further discussed, including: landslides and rainfall distribution, the relationship between landslide and frequency of rainstorm ,the time relationship between landslide and rainfall. The results show that the probability of landslide occurrence and quantity of landslides have positive correlation with rainfall, landslides mainly occur f rom May to September in which the monthly mean rainfall is large.Meanwhile, landslide occurrence is closely related to the characteristics of rainfall of that day and rainfall of early days. When the daily rainfall exceeds 50mm or 10 days accumulative rainfall exceeds 100mm,the landslide is prone to occur and the occurrence rate of the latter is higher.
