超大跨度钢结构输煤栈桥参数化设计研究

摘要

The finite element method was applied to study the parametric design of 80 m large-span steel structure used for coal gallery. The structure of the coal gallery was researched in model simplification, development of parametric program and engineering practice, which solved the difficulties long-term puzzled the technician such as the model simplification and the influence of bending moment on the rod end, thus the calculation efficiency and the accuracy remarkably enhanced. The calculation results proved accurate and reliable via engineering practice, and possessed guidance significance for the engineering design of the coal gallery.%采用有限元方法,对单体长度 80 m 的超大跨度钢结构输煤栈桥进行了参数化设计研究.从模型简化、参数化程序开发及工程案例等方面研究了栈桥结构,解决了长期困扰技术人员的模型简化及杆端弯矩影响等难题,大幅度提高了计算效率及准确性.计算结果经工程实践证明准确可靠,对输煤栈桥工程设计具有指导意义.
