On the basis of practice of construction of 25 000 m3 reservoir, the research and ap- plication of intensive construction in expansion joints and construction technology of the ul- tra-large reservoir is made. According to the characteristics of the engineering and construc- tion difficulties, this paper raises the problem of how to prevent the leakage of expansion joints, formulates reasonable construction method. The scheme, as well as the construction elements and the matters concerned in construction, is introduced in detail. It is found that construction of large reservoirs, in combination with the intensive expansion joints and appli- cation of construction technology, can solve the problem of the leakage. The practice proves that the technology, feasible, will shorten the construction period, reduce cost, improve quality and protect the environment, and it is of green construction technology.
