Abstract: 1 工程概况 黑河象山水库位于黑河市爱辉区法别拉河中游,距黑河72 km,总库容3.34亿m3,建于1992年,大坝为沥青混凝土堆石坝,最大坝高50.7 m,坝长285m.水库建设时由于坝体容重偏低、坝坡陡等原因造成坝体水平变形过大,致使沥青混凝土心墙开裂,漏水严重.故决定增加上下游压重,在原沥青心墙上游修建塑性混凝土防渗墙对大坝渗漏问题进行彻底处理.防渗墙轴线长281.5m,墙厚0.8m墙底嵌入弱风化基岩不小于0.8 m,塑性抗混凝土压强度3~5 MPa,渗透系数K28<1×10-7 cm/s,塌落度度20~24cm,扩散度34~40m,防渗墙面积12 319.96m2.
