摘要
常(德)-吉(首)高速公路上的阿娜隧道是因隧道净距小,双洞间影响较大,故应用二维弹塑性有限元分析方法对其稳定性进行分析研究,计算了衬砌和围岩的内力与位移,进行了变形性状的分析,为高速公路类似的小净距隧道工程设计、施工提供一定的科学依据和参考价值。
In this paper, the authors use two - D elastic - plastic FEM software to analyze the stability of the ANA tunnel in CHANG -JI highway. The internal force and displacement of surrounding rock are calculated. The deformation behavior is also analyzed. The results presented in this paper provide guidelines for design and construetion of similar tunnels.
