薄层软弱岩体流变研究

摘要

Combining with the internal tunnel cracks developing features,according to soft-weak rock rheology mechanism,through finite element analysis software,the paper studies integral stress and deformation tendency of the tunnel surrounding rock,which has provided some guidance for soft-weak rock tunnel design and construction in future.%结合某隧道内裂隙的发育特征，并根据软岩的流变机理，通过有限元分析软件，研究了隧道围岩的整体应力及变形的趋势，为以后软岩隧道的设计和施工提供了参考依据。
