摘　　要：刘老涧船闸是位于京杭运河苏北段上的复线船闸。为解决船闸在二、三线同时泄水时,一线船闸下闸首反向水头过高而使人字门启闭机机构损坏的问题,建立了平面二维水流数学模型对船闸上、下游水流条件进行计算,并按照《船闸总体设计规范》相关要求,判别改善方案通航水流条件的优劣,提出符合实际要求的工程措施。针对天然河道边界复杂等特点,采用非结构三角形网格,利用有限体积法对水流控制方程进行了离散计算。Liulaojian multiline-lock is located at Beijing-Hangzhou Grand Canal. To solve the problem that when the No.2 and No.3 lock to drain, the No.1 lock reverse waterhead is too high to make the lower miter gate hoist mechanism damage, a two-dimensional flow mathematical model is developed to calculate the upstream and downstream flow condition of the ship lock, in accordance with the Code for Master Design of Shiplocks, compare the navigation flow condition of various scheme, and choose the engineering measures which is satisfied the demands. Due to the complex characteristics of the natural river＇s boundary, we adopt the unstructured triangular mesh and use the finite volume method to discrete the flow control equation.
