隧洞抗错断研究中,正、逆断层研究较多,走滑断层研究较少。针对走滑断层引起的隧洞变形破坏、应变分布规律以及上覆围岩的破裂形态等关键问题,以滇中引水输水隧洞为依托工程,制作了隧洞模型开展走滑断层作用下断层隧洞的抗错断模型试验研究,得到隧洞在走滑断层断层错动作用下的结构响应规律。结果表明:①隧道衬砌结构在走滑断层作用下的破坏形式是弯曲张拉破坏以及直接剪切组合破坏,其中剪切破坏是主要破坏形式;②隧道衬砌结构沿纵向以受拉为主,主要集中在活动盘距离错断面⁃0.5

内与活动盘移动方向一致的一侧拱腰;环向应变的影响主要集中在断层错动面附近;③活动盘受断层错动影响范围和剧烈程度均小于固定盘,故断层错动作用下的固定盘是隧洞抗错断控制重点。
Most studies in the literature have focused on the effect of normal and reverse fault on the tunnel lining structural response, and only a few had investigated the performance of tunnel linings subject to strike-slip faults. Focusing on this problem, a model test of tunnel lining performance under strike-slip fault movements was conducted based on the Central Yunnan water conveyance tunnel. The results suggest that the tunnel lining structural failures were mainly due to the combination of bending tension and direct shear, in which the shear failure plays the main role. The tensile deformation was distributed along the tunnel alignment, focusing on the tunnel crown and springlines in the range of -0.5D(D is the tunnel diameter) to 2.0D away from the strike-slip fault zone. The compressive deformation mainly distributed on the tunnel springlines in the range of -0.5D and 0.5D, and kept in line with the movement direction. The influence of circumferential strain was mainly concentrated near the fault zone. Moreover, the tunnel lining deformation in the stationary block was apparently greater than that in the moving wall under strike-slip fault movements. Therefore, more attention should be paid to the structural response of tunnel linings buried in the stationary block.
