Abstract
The number of earth-rock dams and their failures are both the highest of all dam types. For a large number of dangerous situations, multi-angle and multi-level effective safety analysis is urgently required. In this paper, a series of studies on seepage and slope stability of the dangerous clay core dam with danger control and reinforcement (CCDDCR) are investigated by a proposed finite element analysis method. A verification process is finished for this proposed method. A new calculation model is proposed based on an iterative algorithm, and a successful example is then taken on. A reasonable conclusion is given based on the analysis of the three-dimensional finite element model of the dangerous CCDDCR. In view of the conventional concrete, the elastic modulus of the wall is higher, and large deformation and stress and concentration will appear under the water loading, which then affects the anti-seepage effect. Its purpose is to investigate the effect of diaphragm wall material in concrete with low elastic modulus on the anti-seepage wall and its significance in similar reinforcement engineering. The first tentative comparative analysis is taken on by this paper for slope stability analysis between the Lizheng method and FEM method. More useful conclusions can be drawn in future for reference in similar reinforcement projects.
