摘要
大直径泥水盾构常压刀盘作为隧道掘进设备的前端核心部件,结构强度直接影响施工过程中的安全性、连续性与经济性。分析大直径泥水盾构常压刀盘在扭矩、推力与水土压力耦合作用下的受力特点,研究拓扑优化设计中的材料分布调整与减重刚度平衡控制思路,提出高强钢复合焊接与蜂窝几何加强筋等局部强化策略,并经加载平台试验与现场数据对比完成验证。研究旨在形成一套覆盖面板、焊缝、肋节点与支撑环等关键部位的优化方案,提升刀盘整体承载性能、运行可靠性,并延长其疲劳寿命,为大直径隧道施工提供技术支撑。
The large-diameter slurry shield atmospheric pressure cutterhead,as the front-end core component of tunnel excavation equipment,has a direct impact on the safety,continuity,and economy of the construction process due to its structural strength.This article analyzes the force characteristics of the large-diameter slurry shield atmospheric pressure cutterhead under the coupling of torque,thrust,and soil water pressure.It studies the material distribution adjustment and weight reduction stiffness balance control ideas in topology optimization design,proposes local strengthening strategies such as high-strength steel composite welding and honeycomb geometric reinforcement,and verifies them through loading platform experiments and field data comparison.The research aims to develop an optimized solution that covers key areas such as panels,welds,rib nodes,and support rings,in order to improve the overall load-bearing performance and operational reliability of the cutterhead,and extend its fatigue life,which provides technical support for large-diameter tunnel construction.
