小净距公路隧道稳定性数值模拟分析
|
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 construction of similar tunnels.
