Influence Of The Core-wall Structure On Seismic Prevention For Earth Rock-fill Dams

With the inherent traits, the earth and rock-fill dam become the most popular hydor-buildings distributed in the world. Earthquake in china as BaChu and WenChuan were all let so many earth and rock-fill dams damaged differ in degree. As the experience accumulated, the stabilization in the earthquake become one of the most important problem that people concerned of the dam. Study of the influence of the core-wall structure on seismic stability of earth and rock-fill dam was carried out. Some studies as followed were completed.1,After referring to a large amount of literature materials, the history and actuality of seismic stadility analysis was summarized. Introduced the aseismatic design of the earth rock-fill dam,the development of the earth and rock-fill dam,especially the core-wall structure. The important of the aseimatic was pointed out. At the same time,the problems that need to be further studied were put forward.2,A brief summary of the history, factors and steps of solving problems about FLAC. It also gives an introduction about superiorities of FLAC in numerical analysis,models and some useful commands.3,Use FLAC, five different models were established. Take dynamic analysis for five models as the seismic oscillation was incidence vertical. The assessment factors for earth rock-fill dam which as permanent deformation, pore pressure increment, stress level and so on. The computation results are compared and analyzed.Give some important conclusion.4,Give a conclusion to the work and the results that did for this article.Point out the question that still be ,and the future more works are provided.
