Relationship between rainfall and landslides in Wuzhou Guangxi
In order to obtain the rainfall threshold value in Wuzhou, the data of landslide and rain-fall during the year from 2005 to 2012 in Wuzhou prefecture were studied. The scale of landslide, the spatial and temporal distribution of landslide and the relativity between rainfall and landslide were also analyzed. The results show that, under the rainfall, the landslide in Wuzhou prefecture is easy to take place in the superficial layer of slope; that the landslide in Wuzhou prefecture occurs mainly in June each year, and the frequency and intensity of rainstorm reach the maximum value in June, so the relationship between landslide and rainstorm is very close; that the landslide disaster often occurs on the rainstorm day or one day after the rainstorm day; that the critical rainfall for landslide in Wuzhou prefecture is accumulative 300 mm in two consecutive days, and the critical in-tensity of rainfall is 150 mm/d. The results can be considered as a theoretical foundation of warning and forecasting of landslide in Wuzhou.
