    工程設計中，壩型的選取顯得尤為重要，特別對于壩基有深厚覆蓋層的堆石壩，心墻和壩基防滲墻的應力和變形是壩體、壩基最敏感的部位，設計方案是否安全、科學和合理，對大壩防滲和穩定起到至觀重要的作用。本文研究分析了國內外深厚覆蓋層基礎防滲設計、壩基混凝土防滲墻與壩體防滲體銜接形式及工程實際應用效果，為下坂地水利樞紐工程深厚覆蓋層基礎防滲設計的方案選擇提供了參考；在吸收和歸納了國內外堆石壩的設計研究成果的基礎上，對粘土心墻和壩基垂直防滲方案、瀝青混凝土心墻和壩基垂直防滲方案以及粘土斜心墻和壩基水平鋪蓋防滲方案，分別按竣工期和蓄水運行期的不同工作情況進行了有限元非線性計算分析；對左岸高陡邊坡的大壩防滲體與基礎混凝土防滲墻的不同結合型式進行了三維有限元靜力計算分析和研究；對混凝土防滲墻不同彈性模量對墻體應力和變位的影響進行了三維有限元靜力計算分析和研究。通過對不同方案的計算分析和研究，比較全面的了解了各方案壩體，尤其是防滲體的應力和變形分佈規律，為壩型選擇、壩體結構設計、基礎防滲墻與壩體防滲體的結合型式以及塑性區大小的確定提供了重要依據。
