Research on Characteristics and Formation Mechanism of Landslide Disaster in Red Soil Hilly Region of South China

Abstract

The mechanism of landslide hazard in weathering crust of granites in south china was chosen as our research object. Landslides, as a common geo-hazard, can result in huge economic losses and enormous casualties in mountainous regions of the world. Therefore, the mechanism of landslide hazard has become a topic of major interest for both geoscientists and engineering professionals. Take the landslides mechanism as the key problem. Firstly, we will analyze the regularity of its regional differentiation in those area based on the field investigations and the available data in the area according to the features of this kind of landslide. Secondly, we will reveal the growth characteristics and disaster mechanism of landslide by study the relationship between the characteristics of intensity and frequency of landslide and meteorological factors, hydrologic geology, geologic factors, landform and human factors and so on. Finally, based on these result, the regional landslide prediction model was obtained by quantification approach. The final goal is to reduce the landslides risk as low as possible. Our subject will provide scientific basis for risk precaution and disaster emergency response.
