摘要
随着社会经济的发展,安徽省合裕线航道面临极大的通航压力,通过研究开通闸条件,可提高船闸通过能力,缓解船舶拥堵。针对巢湖船闸与裕溪船闸,根据原型观测数据,建立二维数值模型,并最终选择巢湖船闸与裕溪船闸分别在0~30cm、0~60cm水位差进行数值模拟试验,通过开通闸试验研究不同上下游水位差条件下闸室流速、水位演变规律与水位差响应特性,提出开通闸安全运行条件的确定方法。结果表明,巢湖船闸上下游水位差11cm条件下,裕溪船闸上下游水位差40cm条件下,船舶过闸安全可控,具备开通闸条件。
With the development of the social economy,the Hefei-Yuxi waterway in Anhui Province is facing great navigation pressure.By studying the open-gate conditions,the lock capacity can be improved and the vessel congestion can be alleviated.Aiming at the Chaohu Lock and Yuxi Lock,a two-dimensional numerical model was established based on prototype observation data.Numerical simulation tests were finally carried out for the Chaohu Lock and Yuxi Lock with water level differences of 0~30 cm and 0~60 cm,respectively.The open-gate tests were used to study the flow velocity in the lock chamber,the evolution of water level,and the response characteristics of water level difference under different upstream and downstream water level differences.A method for determining the safe operation conditions of open-gate was proposed.The results show that under a water level difference of 11 cm between the upstream and downstream of the Chaohu Lock and a water level difference of 40 cm between the upstream and downstream of the Yuxi Lock,the vessel passage through the locks is safe and controllable,and the conditions for open-gate operation are met.
