基于BIM技术的船闸浮式系船柱结构设计

Structural design of floating mooring column of ship lock based on BIM technology

针对二维设计在处理空间复杂的结构设计及计算问题时手段局限的情况,运用BIM技术在可视化环境下对船闸浮式系船柱进行结构设计,并基于BIM模型进行有限元模拟计算分析,对船闸浮式系船柱结构开展设计研究。建立固接式和铰接式两种结构形式的船闸浮式系船柱BIM模型,分别从结构构造和力学性能分析等方面进行研究。结果表明:铰接式船闸浮式系船柱的系缆小车可以很好地解决系缆高度适应性差等问题,多层系缆小车之间通过连杆柔性连接,降低了埋件的支承反力,并在结构安全性及后期维护等各方面均有较大提升,经多个船闸工程应用实践检验,可为类似工程设计和改进提供参考。

In view of the limitations of two-dimensional design in dealing with spatial complex structural design and calculation problems,building information modeling(BIM technology)is used to carry out the structural design of the floating mooring column of ship lock in the visual environment.Based on the BIM model,the finite element simulation calculation and analysis are carried out to the design research on the floating mooring column structure of ship lock.Two kinds of BIM models including fixed and articulated of ship lock floating mooring column are built,and studied respectively from the aspects of structure and mechanical property analysis.The results show that the mooring trolley of floating mooring column of articulated ship lock can solve the problem of poor adaptability of mooring height well.The multi-layer mooring trolley is flexibly connected by connecting rod,which reduces the supporting reaction of buried parts and improves the structure safety and later maintenance greatly.The design is tested by several ship lock engineering applications,and it can provide references for the similar engineering design and improvement.
