摘　　要：隔河岩坝址基岩具有层状透水、顺河向延伸的断裂构造及岩溶发育、建基岩体透水性不均一、石牌组页岩是可靠的隔水岩层等特性。基岩渗流控制采用由防渗灌浆主帷幕、主排水、坝基辅助排水,两岸山体排水及消力池护坦周边封闭灌浆帷幕、封闭排水等组成的工程布置形式。This paper briefs the seepage charateristics of Geheyan project foundation with carst rockmass, seepage control enginating layout and implementation. Through comparison with several approaches, a foundation seepage control engineering has been optimized and developed. It includes a main curtain and drainage system, auxilary foundation drainage, a drainage system at dam-bankst rockmass, and a perimeter grouting curtain along dissipation poll.
