【摘要】 以九岭隧道为背景,利用数值方法建立了在IV级围岩下不同埋深的隧道仿真分析模型,研究了各埋深中拱顶位移、锚杆最大内力、一期支护最大弯矩、一期支护最大轴力等位移、内力参数随埋深改变的变化规律。更多还原

【Abstract】 In this paper,the simulation analysis model of different burying depth in the IV surrounding rock of Jiuling tunnel is established by using the numerical method.The change of the displacement of arch tip,the maximum inner force of anchor rod,the maximum bending moment and the axial force of supports along with the burying depth varying was studied.These results have some instruction to the tunnel design and construction.更多还原
