Design and Practice of Zhaolaihe Roller Compacted Concrete Double-curvature Thin Arch Dam

摘要

Zhaolaihe River Arch Dam, situated in an extra- unsymmetrical valley, is a logarithmic spiral double- curvature thin arch dam with the maximum height of 105m, crest thickness of 6. 0m, base thickness of 18. 5m, and ratio of thickness to height of 0. 17. In consideration of the topographical, hydrological, meteorological and constructional conditions at the dam site, the dam is built with RCC, so the construction time is shortened and the construction expenses is cut down.
