Abstract
Disclosed is a pressure-bearing device for simulating an excavation unloading test of a high-energy-storage rock mass. The pressure-bearing device comprises pressure-bearing blocks, a casing pipe and sealing rings, wherein the two pressure-bearing blocks are respectively arranged at two ends of a to-be-tested rock mass; the casing pipe can be arranged outside the to-be-tested rock mass and the pressure-bearing blocks in a sleeving mode and is attached to the to-be-tested rock mass and the pressure-bearing blocks; and the sealing rings are arranged outside the pressure-bearing blocks and the casing pipe in a sleeving mode, so that the sealing rings can be tightly pressed on the casing pipe and the pressure-bearing blocks through fastening elements. Further disclosed is a sealing method for simulating an excavation unloading test of a high-energy-storage rock mass.
