电厂粉煤灰场渗流数值模拟

Based on the numerical modeling of steady and transient seepage flow, variation law of total head and how they influence the stability of the side slope of ash dam under two different status（rainfall/ non-rainfall）are analyzed. Seepage flow problem is converted into solution of residue through numerical simulation, among which finite element numerical method is applied; calculation format solution is obtained after discretion. According to the simulation results, some conclusions about variation law of head and osmotic pressure and how they influence the stability of ash dam are drawn.
