Abstract
A device and a method for evaluating damage of high-temperature and high-humidity gas to a surrounding rock porous structure are provided. The device includes a rock sample clamper, a temperature control device, a pressurizing device, a gas mixing injection device, a CT scanning device and a low-temperature nitrogen adsorption device. By simulating the gas rock reaction under the conditions of in-situ temp., pressure and gas, using CT scanning device to visually monitor and analyze the reaction condition of gas and tunnel surrounding rock and the change condition of porous structure, and using low-temperature nitrogen adsorption test to obtain porous structure parameters change condition before and after reaction of gas and tunnel surrounding rock, and the damage evaluation index of the porous structure is established.
