摘要：

为了研究断层错动下盾构隧道力学响应特征，引入Vlasov双参数地基模型，并考虑水平地基摩阻力的影响，提出跨活动断层盾构隧道纵向力学响应解析模型. 以正断层错动工况为例，采用模型试验及数值模拟验证解析模型的合理性，讨论影响隧道结构纵向力学响应的因素. 建立考虑环缝接头塑性变形的三维数值模型，分析环缝接头塑性变形对隧道结构纵向受力与变形的影响. 研究结果表明：解析模型计算得到的隧道纵向力学响应特征与模型试验、数值计算所得规律一致，当不考虑竖向地基剪切刚度时，解析解计算得到的隧道纵向弯矩偏大；相较浅埋土质地层工况，深埋岩质地层对隧道纵向变形限制作用更加明显，导致结构纵向内力增大；隧道与断层之间竖向距离、断层破碎带宽度及结构纵向抗弯刚度有效率等因素均对隧道最大纵向内力影响显著；当考虑环缝接头塑性变形时，在断层错动20 cm工况下，盾构隧道环缝接头已经产生显著的塑性变形，严重威胁盾构隧道的运营安全.

Abstract:

In order to study the mechanical response characteristics of shield tunnels under fault dislocation, an analytical model of the longitudinal mechanical response of shield tunnels under cross-active fault conditions was proposed by introducing the Vlasov two-parameter foundation model and considering the influence of horizontal friction. Taking the normal fault dislocation condition as a case study, the rationality of the analytical model was verified by model test and numerical simulation, and the main factors affecting the longitudinal mechanical response of the structure were further discussed. A three-dimensional numerical model considering the plastic deformation of the annular joints was established to analyze the influence of plastic deformation of the annular joint on the longitudinal force and deformation of the tunnel structure. Results show that the longitudinal mechanical response characteristics of the tunnel calculated by the analytical model are consistent with those obtained by the model test and numerical calculation. When the vertical shear stiffness of the foundation is not considered, the longitudinal bending moment of the tunnel calculated is too large. Compared with the shallow tunnel in soil conditions, the deep-buried tunnel in rock stratum has a more obvious restriction on tunnel deformation and leads to the excessive longitudinal internal force of the structure. The vertical distance between the tunnel and the fault, the width of the fault fracture zone, and the effective rate of the longitudinal bending stiffness of the structure all significantly influence the maximum longitudinal internal force of the tunnel. When considering the plastic deformation of the annular joint, the obvious plastic deformation of the shield tunnel annular joint has occurred under 20 cm fault dislocation, which severely affects the operation safety of the shield tunnel.
