Abstract
The cracks in the concrete of dam core wall cover plate are usually caused by the fact that the con-crete raw materials,concrete strength grade,concrete construction technology and concrete temperature control measures do not meet the requirements of design drawings or construction specifications.Under the circum-stance of excluding the above design and construction factors and comparing the design and construction expe-rience of similar projects,many unprecedented complicated situations,such as high ground stress,temperature stress,grouting lifting,long-term unfilled coverage,appeared in the cover plate of Shuangjiangkou dam core wall,causing the cracks in different conditions appeared in different periods of construction.The engineering construction management unit attaches great importance to the problem of cracks,and organizes expert groups and personnel from participating units to hold special meetings for several times to analyze the causes of cracks,study the corresponding treatment and prevention measures,and achieve good results.关键词
