Numerical Simulation of Rock Slope Toppling Based on Rheological Model
The slope of a hydropower station in the Yellow River has been dumping since the reservoir impounded in 2009. The cumulative deformation of the slope for five years is about 40m, which has posed a serious threat to the safety of the power plant. In this paper, the discontinuous deformation analysis program considering rheology deformation of structural surface is developed based on the Burgers model. With this program, the numerical simulation of the toppling deformation of slope is carried out. The deformation mechanism and failure mode of the slope are analyzed in this paper. It is shown that the impoundment of the reservoir is the induced factor of the slope deformation. The deformation of slope has a strong correlation with the change of water level, but the amount of deformation directly caused by water load is very small. The rising of water level caused the change of effective stress in the slope, which triggered the rheological deformation of the slope. Fully considering the rheological characteristics of structure plane in rock mass, the results of numerical calculation are basically consistent with the results of the actual monitoring.
