| ManLa rockfill dam is located at strong motion earthquake area with 8 degree. It is a rockfill dam with clay core, dynamic response of the dam under earthquake and the earthquake-resistant design is very important for the dam design. The thesis mostly work is mathematical analysis, give some basic information of the research object-ManLa rockfill dam, determinate the research task and the analysis condition. Utilizing pseudo-static method theory, calculated the safety factor for the dam slope, give, a primary conclusion.. Utilizing static finite element method based on Duncan-Chang hyperhola modelfound the static stress riele,make the foundation for hynamical finite element analysis. Utilizing dynamical finite element method based on equipollence linearity model, found the dynamical stress field and the acceleration field, make the foundation for calculated the safety factor of the dam slop with finite element method.Evaluate the conclusion of pseudo-static method and dynamical finite element, and the security of ManLa rockfill dam under earthquake condition, give design scheme of the ManLa dam according to the analysis result. |
