Study on a Water Power Station's Roller Compacted Concrete Dam by Three-dimensional Nonlinear Finite Element Method

In order to improve the dam's global stability under the engineering background of high earthquake intensity and complicated geologic condition,the dam and power plant are combined together.The roller compacted concrete(RCC) dam's stress,displacement and stability against sliding are studied by three-dimensional elastoplastic finite element analysis.And the safety factor of global stability is got by overload method.The finite element calculation result shows that the value,including the distribution,of stress and displacement on dam is rational and the dam's stability against sliding is sound in the mass.Added to these,the result also shows that the engineering measures including transverse joint grouting and combination of hydropower plant and dam have greatly improved the capacity of resisting deformation,stability against sliding of the dam and its seismic restraint performance.
