摘要
汾河二库枢纽工程是我省八五期间的重点建设项目，枢纽中的拦河大坝为碾压混凝土重力坝，对于碾压混凝土重力坝的设计在我省还仅仅是第一次，我们还没有这方面的经验，再加上该坝与常规的坝有所不同，坝址处的工程条件比较特殊，河床狭窄，覆盖层厚达２６～２８ｍ，坝体承受的荷载相当复杂，这就越增加了设计的难度。本文通过对原可研成果进行优化的论述，分析了断面设计中应该注意的问题，为今后类似的工程设计提供了借鉴的经验。
The type of roller compacted concrete gravity dam with downstream slope of 0.8∶1 was designed in feasibility study phase of the Fenhe Reservoir Ⅱ.As the downstream slope is an important factor influencing investment of the project, the adjustment on it has been made based on the feasibility study.The result shows that the downstream slope of 0.8∶1 can be changed into 0.75∶1, and therefore the masonry volume and excavation may respectively be decreased by 25,300 m 3 and 155,300 m 3,reducing a certain degree of the investment.
