As the sample of Yuanliangshan tunnel in Chongqing-Huaihua Railway, based on the full analysis of groundwater specimens, five chemical equations are designed to calculate evaluating data by the relation of activity, equilibrium constant and Gibbs free energy. According to the two criterion of partial pressure of carbon dioxide and reaction direction, the result calculated shows the groundwater has weak corrasion to carbonate rocks, which should be avoided to do harm to tunnel.

以渝怀线圆梁山隧道为实例，通过隧道内地下水取样进行了全分析，其中CO(上标 2-下标 3)离子作为"中间过渡态"离子，由于只存在微小量未被检出；使用水质分析结果数据设计了五个化学反应方程式，通过活度、反应平衡常数及吉布斯自由能之间关系进行热力学计算，依据二氧化碳气体分压P(下标 CO2)与反应进行两个方向化学反应判据开展分析，结果表明地下水具有弱侵蚀性，在隧道工程中应避免其引起危害。
