三峡工程大坝及电站厂房设计中的主要技术问题

Major technical problems on design of TGP dam and powerhouses

泄洪与消能设计、厂１～５号坝段深层抗滑稳定研究、电站压力引水管道和混凝土配合比设计等是三峡大坝及电站厂房设计中的主要技术问题。这些技术问题历数年、数十年之研究，几经众多科研、设计单位刻苦攻关，于今已基本解决确定下来。在大江截流、三峡二期工程即将开始之际，对这些主要技术问题进行概要论述，冀望在今后施工设计中能结合工程实际更进一步完善优化，以创一流设计水平。

Major technical problems on design of TGP dam and powerhouses include the design of flood releasing and energy dissipation, the study on stability against deep layer sliding at No. 1～5 powerplant dam sections, the design of powerplant penstocks and concrete mix proportion, etc. Through hard efforts made by many scientific research and design units for several years, or several decades, these technical problems have been basically solved. On the occasion that the main river closure and second stage construction will soon be started, these problems are briefly expounded in order that their resolutions in construction detail design would be perfected and optimized in accordance with engineering practices, so as to create the first class design level.
