京杭运河台儿庄三线船闸通过能力及闸室尺度

The capacity and chamber dimension of Tai' erzhuang third-lane lock on Beijing-Hangzhou Grand Canal

船闸通过能力的确定应充分考虑货运量及船舶发展要求,以避免成为制约内河航运发展的瓶颈。通过对台儿庄船闸过闸货运量增长和船型现状及发展趋势的分析与预测,基于计算机模拟技术,获得设计水平年船闸一次过闸平均吨位和平均船舶艘次以及闸室利用率,分别计算京杭运河拟建台儿庄三线船闸采用不同闸室尺度时的通过能力,并复核已建船闸的通过能力,最后通过分析货运量预测值、船型发展及船闸节水等条件,选择科学、合理的船闸闸室尺度。

When we determine the lock capacity, the transportation demand and the vessel development need to be taken into consideration to avoid ship lock becoming a bottleneck of the development of waterway transportation.After analyzing and predicting the increase of the throughput of Tai＇ erzhuang lock, the current status and the tendency of vessel dimensions, three main indicators of a lock of the design target year are acquired by computer simulation method, which are the average total tonnages of passing vessels per lockage, average number of passing vessels per lockage and occupancy rate of chamber. Those indicators can be used for calculating the capacities of the planned Tai＇erzhuang third-lane lock under different chamber dimensions, and checking the capacity of the running lock at Tai＇erzhuang.In the end, the reasonable or suitable chamber dimensions from different options are chosen according to the simulation results and considering conditions such as predicted throughput of lock, vessel development and water-saving when lock operating.
