Analysis of the Basic Overview and Characteristics of Research Methods of the Relationship between Rainfall and Landslide

Abstract

The landslide research has continued for more than 100 years, in order to analyze the relationship between rainfall and landslide, the research methods of the relationship between landslide and two main characteristics of rainfall (rainfall and the rainfall process) which affect the stability of the landslide are summarized and analyzed the basic situation and characteristics of the main research methods. Several current problems about research methods of rainfall landslide were put forward:1) complex conditions apply problem;2) the Response rule of landslide surface moisture;3) the variation of surface the water content in different parts;4) The development and change law of landslide thrust force under the action of rainfall need further inquiry;5) lack of factor analysis of variation characteristics and influence of rainfall conditions the development law of landslide displacement and the displacement of landslide in different parts;6) lack of analysis and research interactions between multiple physical effects. Then suggestions and outlooks were given in response to these issues: the data statistics and numerical calculation as the foundation, combined with the response of landslide physical model experiment of multi physical quantity for a comprehensive analysis of the relationship between rainfall and landslide.
