| 摘 要： | 为提高强震区黏滑断层隧道的结构安全性和稳定性,以都汶高速友谊隧道F1黏滑断层段为研究背景,对黏滑断层隧道采用刚柔并济抗减错技术进行研究。研究结果表明:采用结构加强措施抵抗断层黏滑错动影响,结构位移抗减错效果不显著,结构内力的平均抗减错效果在23%~33%之间;施设减错层有利于消减断层黏滑错动对隧道结构的影响,其拱顶沉降、边墙收敛抗减错效果分别达到20%以上,结构内力平均抗减错效果在37%~47%之间,优于结构加强措施;刚柔并济抗减错措施在抵抗及消减断层黏滑错动影响方面效果显著,其拱顶沉降、边墙收敛抗减错效果均能达到30%以上,而结构内力平均抗减错效果达到80%以上。研究成果可为强震区黏滑断层隧道抗震减灾设防设计提供参考。

| Abstract: | To improve the safety and stability of stick-slip fault tunnels in a meizoseismal area, the rigid and flexible compound anti-reducing dislocation technology for stick-slip fault tunnels was analyzed in this paper on the basis of the stick-slip fault F1 of Youyi tunnel in the Dujiangyan-Wenchuan highway. After structure reinforcement measures were taken to resist the influence of fault stick-slip dislocation, the anti-reducing dislocation effect of structural displacement is not obvious, and the average anti-reducing dislocation effect of structural internal force is between 23%-33%. Setting the dislocation reducing layer can help reduce the influence of fault stick-slip dislocation. The anti-reducing dislocation effect of vault settlement and sidewall convergence are over 20%, while the average anti-reducing dislocation effect of structural internal force is between 37%-47%, better than the structural reinforcement measures. Rigid and flexible compound measures have good effects; the anti-reducing dislocation effect of vault settlement and sidewall convergence is over 30%, and the average anti-reducing dislocation effect of structural internal force is more than 80%. The results can provide a reference for the design of seismic disaster prevention and control for stick-slip fault tunnels in meizoseismal areas. |
