随着我国水电事业的发展,兴建的大中型水电站日益增多.单机容量和电站总装机越来越大,主厂房尺寸也随之加大,在厂房的设计和施工方面取得了不少经验和教训.在厂房构造设计方面,对厂房混凝土科学地分缝分块,作好缝间止水设计,对于防止混凝土裂缝,保持结构的整体性,减小渗漏,加快混凝土浇筑速度,都有重要意义.
With the development of hydropower in our country, the construction of large and medium hydropower stations is increasing day by day.As the capacity of single machine and the total installed capacity of power station increase, the size of the main plant also increases, and a lot of experiences and lessons have been obtained in the design and construction of the plant In the aspect of the structure design of the factory building, it is very important for the concrete of the factory building to be divided into different sections and to make the seal between the joints, so as to prevent the concrete from cracking, keep the integrity of the structure, reduce the leakage and speed up the concrete pouring speed .
