摘要

地震引起的永久性地层运动容易导致隧道结构破坏,波纹结构具有良好的大变形能力,在隧道支护中的应用逐渐增多,但是断层错动作用下隧道波纹板支护的力学性能研究较少。本文首先介绍了自主设计的走滑断层模拟装置,利用相似比理论,选取松散沙土和PVC螺旋波纹管进行了跨断层隧道波纹板支护的模型试验,得到了不同错动距离下螺旋波纹管的环向和轴向变形。然后参考规范确定了管土相互作用的土弹簧系数,对断层错动作用的螺旋波纹管进行数值模拟并与试验对比,得到了土弹簧系数的变化规律。最后研究了断层错动下加强肋刚度和土体约束作用对隧道波纹板支护性能的影响规律,结果表明:最大轴向拉压应变发生在断层左右两侧;加强肋刚度增大到一定数值后,波纹板变形和最大错动距离基本保持稳定;波纹板达到相同的变形时,土体约束作用越强错动距离越小。

Abstract

The permanent ground movement caused by earthquake is the main reason for the damage of tunnel structure. The corrugated structure has good large deformation ability, and its application in tunnel support is gradually increasing. However, there are few studies on the mechanical properties of tunnel corrugated plate support under fault dislocation. In this paper, a strike-slip fault simulation device is developed. Based on the similarity ratio theory, loose sand and PVC spiral corrugated pipe are selected to carry out the model test of corrugated plate support for cross-fault tunnel, and the circumferential and axial deformation of spiral corrugated pipe under different dislocation distances is obtained. Then the soil spring coefficient of pipe-soil interaction is determined by the specification. The spiral corrugated pipe with fault dislocation is numerically simulated and compared with the test, and the change of soil spring coefficient is obtained. Finally, the influence of rib stiffness and soil constraint on the supporting performance of tunnel corrugated plate under fault dislocation is studied. The results show that the maximum axial tensile and compressive strain occurs on both sides of the fault. With the rib stiffness increasing to certain value, the deformation of corrugated plate and the maximum ground dislocation distance keep stable. Under the same deformation of corrugated plate, the stronger the soil constraint, the smaller the maximum ground dislocation distance.
