Abstract 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.
