摘　　要：拟建的白石窑枢纽两线船闸是北江中下游重要的通航船闸,口门区水流条件十分复杂。为保证两线船闸口门区利于顺利通航的良好水流条件,建立了整体定床物理模型,在拟定水库调度运行方式下,研究引航道右导墙长度及布置形式对口门区及引航道内水流条件的影响。通过总结实验效果并考虑各种影响因素,认为修改方案IV(上引航道右导墙长392.5 m)较好,其上引航道内均为静水且口门区通航水流条件较好,建议作为推荐方案。The proposed two line lock of Baishiyao water conservancy is important navigation architecture in the middle and lower reaches of Beijiang River and the flow conditions at that entrance area is complex. In order to ensure the two-line ship ],ock port gate area to he conducive to the smooth navigation of good water conditions, the overall fixed-bed physical model was established. And in the intended reservoir operation mode, the influence of the right guide wall length and arrangement of the approach channel on the flow conditions was also analyzed. It is found that the modified project IV （ the right guide wall length 392.5m） performs best; since there is static water in its approach channel and water condition is good at the en- trance area. Then project IV is recommended to be the optimal plan.
