为缓解三峡船闸完建期单线运行带来的航运压力,提出了156.0 m水位船闸由五级运行改为后四级运行以及船舶待闸位置由上游靠船墩移至一闸室的创新设想.借助理论分析、原型调试及实船试验等手段,通过优化各闸首输水方式,解决了船闸四级方案超设计水头运行及一闸室待闸船舶安全的关键技术难题,阐明了一闸室水体波动特性及其与待闸船舶系缆力间的相互关系,提出了符合一闸室待闸特点的运行调度方案.船闸实际运行表明,上述措施大大提高了完建期三峡船闸的通过能力,取得了显著的经济和社会效益.

In order to relieve the navigation pressure caused by the single lane operation of the TGP ship lock during its completion period, the authors put forward two innovatire assumptions:one is to adopt the four-step operation mode instead of the five-step operation mode under water level 156.0 m, and the other is to change the vessels′ waiting location from dolphins to the 1st chamber. Based on theoretical analyses, prototype debugging and full scale ship tests, the key technical problems of the super design head operation under four-step mode and the safety of berthing in the 1st chamber are all well solved by optimizing the conveyance mode of each lock head;the fluctuation characteristic in the 1st chamber and the relationship between it and the berthing vessel′s mooring force are also clarified;and the adequate scheduling scheme considering the above results is put forward finally. The actual operation indicates that the above measures have greatly improved the traffic capacity of the TGP ship lock and achieved remarkable economic and social benefits during the completion period.
