| 摘 要： | 对四川某水电站引水隧洞衬砌混凝土产生腐蚀变质的原因进行了分析，指出环境水对混凝土的硫酸盐及碳酸水侵蚀是最根本和直接的因素。在水电站勘察设计阶段，未对地质环境尤其是水文地质及地下水化学性质进行评价，故而在工程设计方案中，对混凝土的主要原材料水泥的标号及成份要求未考虑环境水对混凝土的侵蚀问题，文章对此提出了相应的防治建议。

| Abstract: | This Paper studied the corrosion of the tunnel concrete at a hydroelectric station,Sichuan. Causing corrosion of the tunnel concrete is water bearing with sulpho-salts. During the prospecting and designing of the hydroelectric station, the hydrogeological geology and the composition of the groundwater were not taken under consideration and the designing scheme did not have correspondent measure to prevent from corrosion of concrete. This paper provide the relevant proposal for remedyin. |
