NUMERICAL SIMULATION OF GROUNDWATER SEEPAGE FIELD IN LANDSLIDE

Most landslides are associated with changes in groundwater levels. Dynamics of groundwater sometimes dictates stability of the landslides. Therefore, it is very important to understand how different factors and engineering mitigation measures affect groundwater flow during treatment of a landslide so that an appropriate measure can be selected. A numerical simulation case study is used to demonstrate the drainage effects on underground tunnel, the groundwater table changes caused by surface water infiltration and anti-sliding piles settings. The simulation results provide an insight into effects of different factors on the seepage field in a slope, which can help optimize design of treatment measures for a landslide.
