Abstract

Based on the percolation theory, fluid- solid coupling equation, using COMSOL Multiphysics, the delayed water inrush model is established. The mechanical behavior of the unsaturated seepage stage, the low velocity stable seepage flow stage and the rapid saturated seepage stage are analyzed by Richard equation, Darcy’s law and Brinkman equation. It is used to determine the elastoplastic area of geological rock and excavation of the safety thickness. It is calculated that when the safety thickness is 46 m, the safety of the project is guaranteed.
