摘要
在阐述宝珠寺水电站工程拦河坝坝址区地质及水文地质条件的基础上 ,对宝珠寺水电站坝基排水孔异常逸出物的分布及其化学成分和矿物成分进行了研究 ,对异常逸出物的工程危害进行了讨论。结果表明 ,在宝珠寺水电站坝基排水孔中 ,异常逸出物主要出现在河床坝段 ,其成分主要是地层岩石中的一些常见元素及常见的成岩矿物 。
On the basis of statement of geological and hydrogeological conditions in the Bao Zhu Si dam area, this article mainly discussed the distribution and the chemical and mineral compositions of the abnormal substances discharged from the drainage well in the dam base. The possible harm of the abnormal substances to the dam engineering is also discussed in detail. Results showed that the abnormal substances emerged mainly in the lowest part of the dam base, the chemical and mineral compositions of the abnormal substances are the common elements and minerals of the earth, and the harm of the abnormal substances to the dam engineering is represented by taking out of large amount of material from the dam base by abnormal substances themselves and in the process of their formation.
