摘　　要：依托某地下水封洞库工程项目,基于现场单孔注水-回落试验数据和水幕连通性测试数据,获得竖直水幕孔岩体渗透性和水幕孔间的连通性,提出基于竖直水幕试验的洞库密封性判断方法,确定竖直水幕孔有效性和洞库密封性,提出竖直水幕系统有效性分析方法,为后续开展竖直水幕系统优化设计提供依据,使水幕系统设计合理,保障洞库水封性。Based on a groundwater sealing cavern project,based on the on⁃site single⁃hole water injection⁃fall test data and the water curtain connectivity test data,the permeability of the rock mass and the connectivity between the water curtain holes were obtained,and the method for judging the tightness of the cavern based on the vertical water curtain test was proposed,and the effectiveness of the vertical water curtain hole and the sealing of the cavern were determined,then the effectiveness analysis method of the vertical water curtain system was proposed,which provided a basis for the subsequent optimization design of the vertical water curtain system,so that the design of the water curtain system was reasonable and the water sealing of the cavern was guaranteed.
