摘要
船闸通过能力是三峡船闸关注的核心问题之一,对三峡船闸挖潜及新通道建设至关重要。基于规范公式法(JTJ305—2001),依据船舶分时段吃水控制标准,提出了船闸分时段通过能力计算新公式。根据三峡船闸运行统计资料,采用提出的公式对其通过能力进行了预测,得出三峡船闸最大通过能力约为1.51亿t。针对三峡船闸通过能力不足的现状,创新性地提出了“船舶分时段配载运输及船闸动态运营管理”的近期提升措施,再次重申了“三峡新通道及配套工程建设”的远期提升措施。
Traffic capacity is one of the core concerns for Three Gorges shiplock.It is crucial to improve the lock capacity and to construct new channels for the Three Gorges shiplock.In line with the Chinese code for master design of shiplocks(JTJ 305-2001),we present a new calculation method for the traffic capacity of shiplock based on time-divided ship draft control standard.According to field operation data,we predicted the lock capacity of Three Gorges shiplock by using the proposed method,and results revealed a maximum capacity of 151 million tons for Three Gorges shiplock.In view of the current insufficient traffic capacity,we put forward such short-term improvement measures as time-divided ship loading and dynamic management and emphasized long-term measures including constructing new channels and supporting projects.
