摘　　要：石膏岩常出现在隧道围岩中,石膏岩在不同溶液环境下溶蚀速率以及溶蚀量不同,溶蚀后的石膏岩力学性质会发生不同的变化,研究石膏岩在不同溶液中的溶蚀与溶出特性显得尤为重要。以湖北竹溪隧道为背景,采用室内溶蚀试验,研究工程区石膏岩在不同溶液中的溶蚀规律。Gypsum rock often appears in the surrounding rock of tunnel.The dissolution rate and amount of gypsum rock are different in different solution environments,and the mechanical properties of gypsum rock after dissolution will change differently.It is very important to study the dissolution and dissolution characteristics of gypsum rock in different solutions.Taking Zhuxi tunnel in Hubei province as the background,this paper studies the dissolution law of gypsum rock in different solutions by indoor dissolution test.

关 键 词：石膏岩 不同pH值溶液 溶蚀速率 微观电镜
