本文简要介绍了初步设计阶段枢纽布置和水工建筑物设计中研究的几个主要方面的问题,诸如对施工期通航方案的研究;结合明渠通航,采用三期围堰挡水,提前发电的研究;安排宣泄特大流量的泄洪设备及其合理位置的选择;以及在大坝设计中采用抽排措施:厂房布置务求紧凑以缩小尺寸;船闸中间闸墙采用衬砌墙方案等。 This article briefly introduces the key design issues such as the layout of hubs and the research of hydraulic structures in the preliminary design stage, such as the research on the navigation scheme during the construction period, the research on navigating the open channel, using the cofferdam water diversion and advanced power generation ; Arrangements for venting excessively large discharge capacity of flood discharge equipment and their rational location options; and the use of pumping in dam design measures: compactness of plant layout to reduce the size;
