The Design and Simplified Calculation of Shading Shed Between Tunnel Groups

文章结合工程实际介绍了隧道群间钢结构遮光棚的设计要点,并对设计方案进行了三维模拟计算,得出在不同荷载组合作用下的内力状态,并进行了强度验算和稳定性验算,通过计算分析可知,案例工程的遮光棚构件截面强度、整体稳定性和构件变形均能满足规范要求,旨在为同类遮光棚结构的设计和验算提供参考。

Combined with engineering practice,this paper introduces the design points of the steel structure shading shed between tunnel groups,and carries out threedimensional simulation calculation of the design scheme.The internal force state under different load combinations is obtained,and the strength checking and stability checking are carried out.Through the calculation and analysis,it can be seen that the cross-section strength,overall stability and component deformation of the shading shed components in the case engineering can meet the requirements of the specification,which aims to provide reference for the design and checking of similar shading shed structures.
