摘　　要：针对清远水利枢纽周边建筑物众多引起的三线船闸平面布置较为复杂的问题,通过对比分析闸位方案、结构预留和空间预留方案,并采用数值模拟的方法,确定了左岸闸位及双线船闸互灌互泄、结构预留的方案。同时,方案还将上游右侧透水导流堤长度延长至350 m,以确保平面布置的合理性。提出船闸平面布置方案应从通航水流条件、与枢纽既有建筑物的相互关系、对已建建筑物结构安全和正常运行的影响、施工期通航、征地拆迁、工程投资等方面综合考虑,对周围建筑物众多、环境受限情况下的船闸布置方案选择具有重要的指导意义。In view of the complex layout of third-line ship lock caused by the numerous buildings around the Qingyuan Hub,this paper identifies a layout scheme by comparing and analyzing the lock location options,structural and space reservation options and by using numerical simulation methods.The scheme includes location on the left bank,double-line ship lock with mutual filling and emptying and structural reservation.Meanwhile,the scheme extends the length of the upstream right permeable diversion dike to 350 m to ensure a reasonable layout.It proposes that the layout of the ship lock should be considered from the perspective of navigable flow conditions,interrelationship with existing buildings in the hub,influence on the structural safety and normal operation of the built buildings,navigation during the construction period,land acquisition and demolition,construction investment,etc.,which is an important guiding significance for the selection of the layout of the ship lock in the case of many surrounding buildings and environmental constraints.
