摘　　要：塑性混凝土防渗墙是一种塑性墙体结构,具有一定的抗压强度和抗渗能力,有较低的弹性模量,并可人为地控制,抑制渗漏、管涌等。塑性混凝土防渗墙不仅能有效截断坝(土)体的渗透水流和降低坝(土)体中渗透坡降,还能承受一定的垂直和水平荷载,能适应周围坝(土)体变形、地基变形,大大减小墙体内应力,避免墙体开裂,且可节约水泥,降低工程防渗造价,效果显著。Plastic concrete cut-off wall is a plastic wall structure with certain compressive strength and impermeability capacity,and lower modulus of elasticity,which can be controlled artificially for curbing leakage,piping,etc. Plastic concrete cut-off wall not only can cut off seepage flow of the dam（ soil） body and lower seepage slope in the dam（ soil）body,but also can withstand certain vertical and horizontal load. It can adapt to the surrounding dam（ soil） body deformation and foundation deformation,thereby greatly reducing stress in the wall,avoiding wall cracking,saving cement and reducing the cost of the engineering seepage control with remarkable effect.
