Abstract The glauberite salt rock samples are scanned at various corrosion time by the μCT225KVFCB-type high-precision micro-CT test system. According to the different ray attenuation coefficient changes in the whole corrosion process，the corrosion damage law of glauberite salt rock is studied from the perspective of meso- structure. The research results show that the density damage and pore ratio of the glauberite salt rock samples increase gradually，but the total specific surface area declines linearly with corrosion time. Meanwhile，the change in specific surface area of corrosion route way is particular，and it increases at first and then decreases. These research results have a very important significance for studying the output capacity，production efficiency and ground settlement of in-situ corrosion mining of glauberite salt rock deposit.

Key words： rock mechanics glauberite salt rock corrosion micro-CT test damage
