摘要
开展了pH值、温度等环境要素对隧道岩样溶蚀影响的实验。结果表明温度对隧道岩样溶蚀影响呈现非单向特征，25℃时溶蚀率最大。pH值对岩样溶蚀率影响最为明显，酸性条件是中性、碱性条件下溶蚀率的20～400倍。相比较而言，在隧道较常见温度与pH值条件下，隧道出口段岩样比其他位置更易被溶蚀。
This experimental research focus on environmental elements such as pH, temperature influence sample dissolution of the tunnel.Results show that the temperature influence on tunnel rock sample dissolution very little,when 25℃ the corrosion rate is the largest, pH of sample dissolution rate influence is most obvious, as neutral ,alkaline conditions 20-400 times. In comparison, the tunnel under the condition of the more common temperature and pH, the export of tunnel rock more easy be corroded.
