摘要
文章基于大型通用软件ANSYS,以深埋条件下隧道为例,采用荷载结构法,对考虑仰拱作用的各级围岩两车道公路隧道衬砌结构进行计算,求解其强度安全系数并进行相关安全分析,所得结论可为工程人员参考。
Based on the large general-purpose software ANSYS, and with the deep buried tunnel as the example, the article used the load structure method to calculate the lining structure of all levels of surrounding rock two-lane highway tunnels with the consideration of inverted arch effect,solved its strength safety factor and conducted the related safety analysis,and the conclusion can be used as the reference for engineering staff.
