A Research For Process Of Earth Dam Slope Failure Based On Continuous Block Theory

In our country there is a considerable portion of the small earth dam due underdisrepair, geological and hydrological conditions changed and other factors which makeslope landslides occured frequently, affect the safety of life and property of the peopleof earth dam nearby area. For those dam which shoulder the lives and property of thepeople downstream, depending on the design method of stability specification used tocontrol the stability of the dam is not enough, we also need to find a way to change inthe future due to various factors that landslide accident will happen to long-termforecasting and disaster assessment in order to make the appropriate preparations. Thisarticle is based on the modeling of landslide domestic computing research, using acalculation based on energy conservation to simulate a continuous block theorylandslide. Compared with the general theory of continuous block, the theory used inarticle is from the energy conservation perspective, not only is the potential conversionof kinetic energy taken in considering, but also the deformation caused by friction andenergy loss. Compared to only consider the kinetic and potential energy into acontinuous block theory, considerations of the theory mentioned above is morecomprehensive, broader scope. The article first describes the details of a continuousblock theory based on the energy point of view, the theory is then applied to thetheoretical model and the actual model of the two models, since the simulation resultsare compared with the actual results to prove the theory and algorithm accuracy.Finally, the theory is applied to numerical simulation of an earth dam landslide instance,the nature and level by changing the filling of the dam constitutes a combination ofdifferent conditions, and thus the destruction of different process conditions and failuremechanism of earth dam slope.
