【摘要】 内蒙古利民矿井主斜井驱动机房至原煤仓栈桥结构型式为钢桁架。从栈桥结构的选型、上下弦支撑布置方式、细部构造等方面对钢桁架的设计进行了研究。并通过PKPM二维模型与MIDAS有限元模型的计算结果进行对比分析,得出了钢桁架设计的一些结论,以期对实际的工程设计和施工有所帮助。更多还原

【Abstract】 The research object of this paper is the coal-conveyer-gallery of the driving room of driving device to the raw coal bunker. Through the comparative putative analysis of the space model and plane model,the results of which have been analysed and summarized can be used in engineering design and provides some references for the construction.更多还原
