Application of Seepage Stress Coupling Model Considering Gas Action in Huangbizhuang Reservoir
摘要
Abstract
The porous media coupling models established currently usually consider gas as incompressible,which unable to describe the gas transport process,and unable to reflect the effect of gas on water infiltration and solid deformation.Based on the theory of porous media and the principle of effective stress,a stress coupling model of solid-liquid-gas three-phase seepage in porous media is proposed,which is coupled with the improved conservation level set(ICLS)method and considers the compressibility of gas.In this paper,the method is applied to the seepage stress coupling analysis of the bubbling phenomenon in front of the dam of Huangbizhuang Reservoir,and the processes of solid deformation,water infiltration and gas migration after the sudden rise of water level are simulated.The calculation results show that this method can describe the migration process of water and gas phase and the stress coupling process of seepage easily and intuitively,and the simulation results are basically consistent with the actual observation results.关键词
