System for predicting landslide using rainfall infiltration characteristics and method therefor

摘要

The present invention relates to a system and method for predicting a landslide using rainfall infiltration characteristics, wherein the risk of landslides is quantitatively determined by considering rainfall, geometric characteristics (slope) and engineering characteristics (unsaturation characteristics) And a method for predicting the same. In order to achieve the above object, the present invention creates a numerical altitude model based on digital terrain data of a target area and generates a thematic map of slope angle based on the contour vector layer of the generated numerical altitude model A slanting motif creating section; The penetration stability analysis unit performs infiltration stability analysis according to rainfall characteristics including rainfall intensity and rainfall duration using infinite slope model that can reflect the slope, and hydraulic and mechanical properties of unsaturated soil. And generating a steep slope collapse prediction model by combining the slope theme generated through the slope theme generating unit and the analysis result through the penetration stability analyzing unit to generate a steep slope collapse prediction model, A risk derivation unit for quantitatively analyzing the slope gradient extracted through the generation unit; .
