| 摘 要： | 西北地区的环境不中常含有大量的硫酸盐，金属硫休物也有广泛分布。侵蚀介质对砼的侵蚀作用，易发生在不工建筑、引水工程以及浸没在地下水位以下的各种砼的地下构筑物中。通过对黄铁矿及硫酸盐的破坏影响机制进行初步分析表明，其对边坡稳定、渗流稳定及水工建筑物安全均可能造成重大危害，应引起广泛重视。

| Abstract: | There is much sulphate in environment water in northwest China, where metal sulphate is also wide spreaded. Erosion action of erosion media on concrete is easily occurred in hydrau1ic structure diversion works and immersed underground structure. By preliminary discussion on destructive influence mechanism of pyrite and sulfate, the results show it would make serious harm to slope stability,influent stability and the safety of hydraulic structure,which should be paid much attention. |
