摘　　要：本文简要说明了大黑汀大坝 2 8孔溢流堰面混凝土的缺陷和破坏情况 ,通过对堰面混凝土钻孔取芯样、压水实验、电镜及能谱分析等方法进行了宏观和微观实验研究 ,对堰面混凝土的破坏成因给予了初步分析和评定 。This paper describes defects of and damage to the concrete of the 28th hole of Daheiting dam spillway. Through core sampling from the concrete weir, hydraulic pressure experiment, electric glass and energy spectrum analysis, etc macroscopic and microscopic experiment study is performed, and the causes of the damage to the concrete weir are primarily analyzed and evaluated, providing a good theoretical basis for later adoption of appropriate methods and treatment of weirs.
