摘　　要：考虑化学作用的岩土力学性质研究及其稳定性问题已成为国内外学者关注的焦点。采用酸性环境下的加速试验,研究了钙质胶结砂岩受酸腐蚀后在不同时段单轴压缩应力作用下表现出来力学特性,揭示了砂岩腐蚀过程和受酸腐蚀机制,其目的是为酸雨环境下,研究岩体的物理力学性质提供可以借鉴的思路和方法。An extensive attention has been paid to the effect of chemical solution on rock properties. The physical and mechanical characteristics of calcareous cementitious feldspathic sandstone specimens subjected to hydrochloric acid attack were investigated by means of the accelerated corroded test. The progressive and deteriorative mechanism of the specimens in different acid solutions is revealed. The results indicate the acid environment has strong influence on rock mechanical properties.
