| 摘 要： | 目前国内外对棚洞结构的动力分析还鲜见报道。该文结合实际工程。利用FLAC^3D软件对提出的新型棚洞结构在地震荷载作用下的力学响应进行了研究。通过计算得出了该棚洞结构在不同地震荷载作用下的位移云图和位移时程曲线，进而找出了结构的薄弱部位，对新型棚洞工程设计、施工和加固有一定的参考作用。

| Abstract: | The studies on the mechanical analysis of shed-tunnel structure have been less reported domestically and abroad so far. In light of an actual project, this paper investigates the mechanic response of the new shed-tunnel structure in case of earthquake load with the help of the FLAC3D software. Displacement cloud chart and displacement time interval curve in different earthquake load are obtained by calculation. In addition,the unsustainable part of the structure is found which can provide some references on the structure design, construction and reinforcement of the new shed-tunnel. |
