On seismic dynamic stability of No. Ⅱ deformation body by Newmark Method for Laziwa Hydropower Project
No.Ⅱ deformation body is located downstream to the left abutment for Laxiwa hydropower project, and its stability mainly affects the safety of left abutment and the zone of flood energy dissipation. The analysis of dynamic stability was made for No. Ⅱ deformation body by Newmark method and the process safety coefficient and its displacement were obtained. The comparative analytic computations of the above results were carried out between conventional pseudo-static method and 3-D finite element method, and the feasibility and reliability in the analysis of earthquake dynamic stability of the slope by Newmark method was discussed. It is concluded that it can basically satisfy design standards of No. Ⅱ deformation body under earthquake condition.
