Safety Analysis of Static & Dynamic Method in Foundation Pit Considering Unsaturated Seepage

Abstract:

In order to study whether foundation pit is stable or not after excavation, the article adopted the Duncan E-B model to make static analysis for the excavation scheme which considering the soil consolidation settlement and to make dynamic analysis under the action of earthquake wave of EL Centro. To make a slope stability of foundation pit analysis by calculating static and dynamic boundary conditions which further coupled with the Newmark method. The main study is the foundation settlement and earth-rock dams, slope stability of foundation pit conditions that considering unsaturated zone seepage conditions of earth-rock dams after the excavation. The results indicated that: in the static & dynamic analysis, the distribution about settlement is reasonable, earth-rock dam and foundation pit slope is in the steady state, the excavation scheme is reasonable and feasible.
