In this project, the maximum height of the dam is 81m, but the deep overburden in the riverbed has the depth of 147. 95m which is about two times of the maximum height of the dam body, so the seepage and liquefaction prevention of the dam foundation becomes the key and important problem in the design of the dam project. the static stress and deformation under three different projects - horizontal blanket project, clay core project and asphalt core project - for the dam is analyzed comprehensively. the damage that may be induced by variable factors on the dam body in time of engineering completion and water impounding operation period is seriously studied
其次，將這一模型用於分析下坂地水利樞紐工程，由於該工程河床覆蓋層深度最深達147 . 95m ，是壩體高度的近兩倍左右，壩基的滲流和液化成為壩體安全主要問題，本文對該壩的三種設計方案即水平鋪層防滲方案、粘土心墻防滲方案及瀝青心墻防滲方案的靜態應力位移及壩體在竣工期、蓄水期等各個階段可能產生的破壞進行了認真研究。 -
By virtue of the design features of the mania dam, this paper studies the dynamic characteristics of the dam materials. by comparison with other similar projects, it presents a curve for dynamic characteristics of clay core materials and rockfill materials, makes analysis on the dam ' s plane dynamic response by finite element method, calculates the dam ' s seismic acceleration, the dynamic shear stress of the rockfill, and the dynamic stress of the cutoff wall in the overburden layer
本文針對滿拉土心墻堆石壩的設計特點，進行了築壩材料動力特性試驗研究，通過與相關工程對比給出了心墻料和堆石料的動力特性曲線，採用有限元方法進行了大壩平面動力反應分析，計算了大壩的地震加速度、堆石體動剪應力及覆蓋層防滲墻的動應力。 -
