超超临界燃煤机组侧煤仓有限元分析及设计

Finite Elemet Analysis and Design of Side Bunker Structure of Advanced Ultra-supercritical Coal-fired Units

  • 摘要:
      目的  超超临界燃煤机组主厂房侧煤仓高度较高、荷载巨大,是结构设计的难点,以实际工程为例,尝试解决这一难题。
      方法  通过SAP2000、SATWE两种软件对结构进行有限元分析,针对侧煤仓结构选型、抗震性能计算分析、基础设计、剪力墙分析设计、煤斗大梁分析设计等关键问题进行较为详细的分析和论述。
      结果  结果表明:单跨侧煤仓剪力墙结构选型是合理的,煤斗大梁的配筋具备深受弯构件的特征,需按深受弯构件进行设计。
      结论  所提供的分析与论述为同类工程提供较好的参考。

     

    Abstract:
      Introduction  For the height is higher, the loads are huge, side bunker is the difficulty of structure design in advanced ultra-supercritical coal-fired units. The paper aims to solve this problem.
      Method  SAP2000 and SATWE were used to analysis the structure, structure seletion and seismic performance calculation and analysis、analysis and design of base、shear wall and coal beam were analyzed.
      Result  The results show that the type selection of shear wall structure of single span side coal bunker is reasonable, and the reinforcement of coal bunker girder has the characteristics of deep bending component, which needs to be designed according to the deep bending component.
      Conclusion  The analysis and discussion provided in this paper provide a better reference for similar projects.
