| description | The invention provides a rural house building site selection method based on landslide disaster risk zoning, and the method comprises the steps: obtaining a stability coefficient expression of each grid unit body at different depths through employing a TRIGRS model in combination with the change of underground pore water pressure; the method comprises the following steps: according to a regional rainfall condition and based on a rainfall infiltration theory, obtaining hydraulic power change in a slope, according to random distribution of rock-soil body strength parameters, generating N groups of random numbers according with the random distribution of the rock-soil body strength parameters by utilizing a Monte Carlo method, and substituting the random numbers into a grid unit stability coefficient expression, n stability coefficient results are obtained for the same grid unit body, M numerical values smaller than or equal to 1 exist in the N stability coefficient results, the instability probability of the gr |
