长江三峡水利枢纽通航建筑物设计

长江是中国最大的通航河流,发展航运是兴建三峡工程主要综合效益之一.三峡通航建筑物由目前世界上设计总水头和阀门工作水头最高的双线五级大型船闸、世界上提升高度和提升重量最大的一线大型垂直升船机和施工期一线临时通航船闸3个工程组成.扼要介绍了三峡通航建筑物设计的主要技术难点,通航建筑物在枢纽中的布置,双线五级船闸的建筑物、机电设备及输水系统布置,闸首、闸室结构和高边坡设计,垂直升船机和临时船闸主要建筑物、金属结构、机电设备的布置,主要结构和设备的设计.

On navigation structure design of Three Gorges Project of the Yangtze river

The Yangtze river is the largest navigation river channel and the navigation development is one of comprehensive benefits of TGP's construction.The TGP's navigation structure is consisted of 3 works,i.e.the large type of double lane and 5 step shiplock with largest design water head and operation water head of valve,the large type of vertical shiplift machine with largest lifting height and weight,the temporary navigation shiplock.This paper briefly presents the main difficult issues in the design of TGP's navigation structure,the layout of navigation structure in the project,the structures of double lane and 5 step shiplock,the layout of mechanical and electric equipment and lock filling and emptying system,the design of chamber structure and excavated high side slope,the main structure,metal structure,mechanical and electric equipment layout of vertical shiplift and temporary shiplock.
