摘　　要：为进一步挖掘三峡船闸的通过能力,提出4.5 m吃水大长宽比船舶同步移舶技术。通过系统性的实船试验,从船舶停泊安全和航行安全两方面探讨该技术的可行性。结果表明,船舶系缆力在船舶制动停靠、闸室充泄水、人字门开启3个典型时段均超过了200 kN,系缆力与船舶排水量、闸室惯性超高(降)和初始水深密切相关,系缆方式对系缆力无明显影响;基于实测数据建立的下沉量公式预测,4.5 m吃水大长宽比船舶同步移舶航速小于1 m s时不存在触底风险;大型船舶的停泊安全是制约进一步挖潜三峡船闸通过能力的关键问题,船舶的航行安全不是控制因素。For further increasing the passage capacity of the Three Gorges ship lock,we propose the synchronous navigation technology of large aspect ratio ships with 4.5 m draught.We discuss the feasibility of this technology from two aspects including ship berthing safety and navigation safety through systematic actual ship test.The results show that the mooring force of the ship exceeds 200 kN in three typical periods of braking stop,filling and discharging the lock chamber and opening the miter gate.The mooring force is closely related to the ship displacement,the inertia water level difference and the initial water depth of the lock chamber,and there is no obvious influence on the mooring force of the mooring type.Based on the ship sinkage formula built by the measured data,it is predicted that there is no bottom contact risk when the speed of synchronous navigation ships with 4.5 m draught is less than 1 m s.The berthing safety of large-scale ships is the key problem that restricts the further increase of the capacity of Three Gorges ship lock,while the safety of navigation is not the control factor.
