摘要
为探究双断面错动所诱发的隧道衬砌结构位移及其受力响应。文中基于MIDAS GTS NX有限元软件,分析了隧道衬砌结构在断裂带活动条件下的应力分布及其变形规律。结果表明不同于单断裂错动,随着断裂带错动的发生隧道衬砌结构的轴应力将集中分布在断裂附近且拉、压应力成对出现,同时剪切应力则集中分布在断裂附近的左、右拱腰位置并呈对称分布。研究成果可为类似工程设计和工后隧道衬砌结构的维护提供借鉴。
In order to explore the displacement and stress response of tunnel lining structure induced by double section dislocation.this paper analyzes the stress distribution and deformation law of tunnel lining structure under the condition of fault zone activity,based on MIDAS GTS NX finite element software.The results show that,different from single fracture dislocation,with the occurrence of fracture zone dislocation,the axial stress of tunnel lining structure will be concentrated near the fracture,and the tensile and compressive stresses will appear in pairs,while the shear stress will be concentrated at the left and right arch waist near the fracture and distributed symmetrically.The research results can provide reference for similar engineering design and maintenance of lining structure after construction.
