Abstract In order to investigate the physicochemical damage mechanism and dynamic mechanical properties of annular sandstone specimens under weak acid environment，the specimens of annular sandstone with outer diameter of 50 mm and inner diameters of 0，5，10，15，20 and 25 mm were corroded by weak acid solution(pH = 5) for 28 d，and the basic physical parameters，mineral compositions and microstructures were tested，and impact compression tests were carried out by using split Hopkinson pressure bar(SHPB) test device. The impact compression test was carried out using SHPB test device. The results show：Corrosion of the annular sandstone specimen by a weak acid solution produced Na+，Al3+，Fe3+，and precipitates such as silicic acid(H2SiO3)；Specimen mass loss rate，volume expansion rate and density reduction rate all increase with increasing pore size；with increasing pore size of annular sandstone specimens，the dynamic compressive strength and dynamic elastic modulus show a decreasing trend of exponential function，the dynamic peak strain and the average strain rate show a quadratic and linear trend of increasing，respectively，and the degree of specimen impact crushing is intensified；Compared with the specimens of annular sandstone specimens eroded by neutral solution(pH = 7)，the specimens showed a decrease in dynamic compressive strength and dynamic elastic modulus，and an increase in dynamic strain and average strain rate. The acid-rock reaction causes the sandstone to generate new substances，and the larger the pore size，the easier it is for acid ions to enter the interior of the specimen，and the more serious the deterioration of its structural damage is，resulting in a significant decrease in the kinetic properties.

Key words： rock dynamic mechanics weak acid corrosion cyclic sandstone specimen dynamic compression SHPB test apparatus
