Rural house building slope cutting landslide disaster risk evaluation and management method

The invention provides a rural house building slope cutting landslide disaster risk evaluation and management method, and the method comprises the steps: calculating the stability coefficient of each grid unit body at different depths in a region through a TRIGRS model, obtaining a region damage probability distribution diagram through the combination of a Monte Carlo method, converting the grid units into slope units through an ArcGIS platform, obtaining a region risk distribution diagram, and carrying out the evaluation of the slope cutting landslide disaster risk. Determining whether house building is allowed in the area according to the danger; cutting slopes are divided into soil cutting slopes and rock-soil mixed cutting slopes, cutting slope stability coefficients and potential sliding areas under different parameter combinations are calculated based on Geostudio simulation, and whether slope cutting is allowed or not is determined according to the cutting slope stability coefficients; obtaining a hous
