摘要为探究弱酸环境下环状砂岩试样物理化学损伤机制和动态力学特性，对外径50 mm，内径0，5，10，15，20，25 mm环状砂岩试样采用弱酸溶液(pH = 5)腐蚀作用28 d，测试基本物理参数、矿物成分和微观结构形貌，利用SHPB试验装置开展冲击压缩试验。结果表明：经弱酸液腐蚀环状砂岩试样，生成了Na+，Al3+，Fe3+和沉淀物硅酸(H2SiO3)等；试样质量损失率、体积膨胀率和密度减少率均随孔径增大而增大；随环状砂岩试样孔径增大，动抗压强度和动弹性模量均呈指数函数下降趋势，动峰值应变和平均应变率分别呈二次函数和线性函数增大趋势，试样冲击破碎程度加剧；与中性溶液(pH = 7)侵蚀环状砂岩试样相比，环状砂岩试样动抗压强度和动弹性模量降低，动应变和平均应变率增大。酸–岩反应使砂岩生成新物质，孔径越大酸离子越容易进入环状砂岩试样内部，其结构损伤劣化越严重，导致动力学性能下降明显。

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
