摘　　要：大藤峡水利枢纽工程是打通西江亿吨黄金水道的关键项目,坝址河段航运要求高,货运量大,通航建筑物船闸的总体设计布置对整个枢纽的布置方案、货运量、运行管理、投资起着至关重要的作用。对于船闸的总体设计,首先根据工程区地形地质条件,结合枢纽布置要求选择船闸位置,在此基础上,对闸首、闸室、输水系统、上下游引航道、口门区及连接段、待闸锚地等进行设计,并根据模型试验成果优化输水系统结构尺寸及口门区整流措施。大藤峡船闸无论是规模、水头还是水位变幅条件和水力指标要求均达到了国内外已建船闸的最高水平,其总体布置可为大尺度、高水头船闸的设计提供一定的参考作用。The Datengxia hydro project is a key project to open the 100-million-ton golden waterway of the Xijiang River,with high navigation requirements for the dam-site reach and a huge freight volume.The general design layout of the navigation structure ship lock plays a vital role in the layout scheme,freight volume,operation management,and investment of the whole hydro project.For the general design of the ship lock,the position of the ship lock is first selected according to the topographical and geological conditions of the project area and the layout requirements of the hydro project.On this basis,this study designs the lock head,lock chamber,water conveyance system,upstream and downstream approach channels,entrance area and connecting section,anchorage to be locked,etc.Additionally,the structural dimensions of the water conveyance system and rectification measures in the entrance area are optimized according to the model test results.The Datengxia ship lock has reached the highest level of ship locks built at home and abroad in terms of the scale,water head,water-level variation amplitude conditions,and hydraulic index requirements.Its general layout can provide a certain reference for the design of large-scale and high water-head ship locks.
