摘　　要：我国岭南地区许多小型水电站大坝长期在保持运行,由于早年设计标准低,长期运行存在着许多病险隐患,需要定时进行除险安全复核评估。以东乡水电站大坝工程为背景,对水库的混凝土和进水结构检测,评估了工程结构稳定和质量安全,重点对防洪和渗流稳定性进行复核验算和评价,得出了大坝安全评价为二类,给出了重点进行除锈保养和定期监测的建议。Dams of many small hydropower stations in Lingnan region of China have been in operation for a long time. Due to the low design standards in early years, there are many potential dangers in long-term operation, so it is necessary to carry out regular safety review and evaluation. Taking the dam project of Dongxiang Hydropower Station as the background, the structural stability and quality safety of the reservoir are evaluated by testing the concrete and intake structures. The checking calculation and evaluation of flood control and seepage stability are emphasised. It is concluded that the dam safety evaluation grade is the second type dam, and the suggestions for key rust removal maintenance and regular monitoring are given.
