中文摘要:
      船闸三角闸门多采用空间网架结构,对于34 m口门船闸而言,采用三角闸门形式尚属首次。为提高闸门结构设计合理性和安全可靠性,结合合裕线裕溪一线船闸扩容改造工程三角闸门的设计实例,从门体结构、支承运转装置、防撞系统、止水系统4个方面对大口门船闸三角闸门设计中须解决的关键技术难点进行分析,选取两组设计水位组合对闸门空间结构进行有限元仿真分析,并对顶、底枢结构进行针对性设计,同时在运转件表面强化工艺、防撞系统结构形式、不同部位的止水设计等方面提出解决方案。结果表明:闸门各结构部件受力在允许范围之内,运转装置安全可靠,止水结构适应性良好,均满足使用要求。
英文摘要:
      The space grid structure is mostly adopted to the sector lock gate of ship lock,and the sector lock gate is the first time to be adopted in the design for 34 m ship lock. To improve the design rationality and safety reliability of gate structure,we combine with the design example of the sector lock gate of the expansion and reconstruction project of Yuxi first ship lock on Heyu line,analyze the key technical difficulties in the design of sector lock gate of the large entrance ship lock from four aspects including the main structure of the gate,the supporting and moving parts,the anti-collision system and the water sealing system,perform finite element simulation analysis of the spatial gate structure for two design water level combinations,design top and bottom pintle structures specifically,and propose solutions in the aspects of surface strengthening technology of moving parts,structural type of anti-collision system and water sealing design. The results show that the stresses of all parts of the gate are within the allowable range,and the moving parts are safe and reliable,the water sealing system has good adaptability. Overall,all of them meet the requirements of use.
