【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。更多还原

【Abstract】 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.更多还原
