水力发电厂水工建筑物首轮安全性评价综述

The Summarization of First-run Safety Evaluation for Hydraulic Structures of Waterpower Plants

文中就中国大唐集团公司和国投电力公司所属的14个大中型水力发电厂水工建筑物首轮安全性评价工作查评中发现的若干共性问题,例如部分水工建筑物设计标准偏低、水工混凝土建筑物普遍存在裂缝、泄水建筑物未经历较大洪水考验、电站进水口堵塞与尾水淤积较严重、水电厂监测设施不全、防汛工作较薄弱等问题进行了总结和评述,并提出了一些建议,可供类同水力发电厂借鉴。

Some common problems, found in the first-run safety evaluations for the hydraulic structures of 14 big waterpower plants which are managed by the Datang Group Company and Government Investment Electricity Company, are discussed and summarized in this text. These problems include the lower design standard, ubiquitous cracks in the structures, no testing by big flood, blocking in the entrances and severe deposition in the draft tubes, lack of monitoring equipment, poor flood prevention, and so on. After that, some advice is given in order to be referred by other plants.
