METHOD AND SYSTEM FOR ANALYSING LANDSLIDE CONSIDERING ANTECEDENT RAINFALL AND IN-SITU MATRIC SUCTION

摘要

A method for analyzing a slope by using a computer according to embodiments of the present invention comprises the steps: (a) setting rainfall conditions including soil properties and unsaturated characteristics of an analysis area, antecedent rainfall and current rainfall; (b) determining a steady-state pore water pressure distribution in accordance with a first matric suction by using one-dimensional infiltration model; (c) determining a steady-state water pore pressure distribution by using one-dimensional infiltration model, and a pre-pore water pressure distribution in accordance with antecedent rainfall conditions; and (d) evaluating a slope safety factor based on a pre-pore water pressure distribution.
