摘要:

为了解红层泥岩隧道穿越富水断层破碎带时衬砌结构的受力状态,对甘肃某在建隧道邻近富水断层带的红层泥岩断面开展了围岩、初支钢拱架和二次衬砌(二衬)混凝土应力的长期原位监测,分析了富水断层突水突泥治理期间红层泥岩隧道结构的受力规律。结果表明:受富水断层的水分渗流影响,施工期隧道拱顶的围岩压力最大,为498.28 kPa,在二衬施作后,拱顶围岩压力逐渐降低,而仰拱承受围岩压力持续增加,仰拱最大围岩压力达352.75 kPa。初支钢拱架具有明显的非对称分布,拱架外侧受力呈“上大下小”分布特征,最大压应力位于拱顶与右拱腰,右拱腰受断层活动产生的压应力影响而弯曲破坏; 拱架内侧受力呈“上小下大”特征,最大压应力位于仰拱左侧。二衬混凝土总体满足隧道安全系数要求,受富水断层直接影响的拱顶与右拱腰混凝土承受最大压应力; 由于施工结束后断层破碎带向隧道基底围岩的持续水分渗透,仰拱混凝土应力稳定时间较长,在长期运营中具有底鼓风险,在隧道运营中应重点关注隧道基底变形。研究结果为后续类似隧道工程的加固方案优化和排水方案确定提供相应参考。

Abstract:

To explore the stress state of lining structures in a tunnel traversing a water-rich fault zone, the long-term in-situ stress monitoring of surrounding rock, initial steel arch frames, and secondary lining concrete were conducted in a red-bed mudstone section of a tunnel under construction in Gansu. The force patterns of the tunnel structure were analyzed during the water and mud outburst control period in the water-rich fault. The results show that moisture seepage from the water-rich fault results in a maximum surrounding rock pressure of 498.28 kPa on the crown during construction. Following the application of the secondary lining, the pressure decreases gradually, but the pressure on the inverted arch continues to rise, reaching a peak of 352.75 kPa. The initial steel arch supports display a clear asymmetrical force distribution, with greater force on the upper outer side than the lower. Maximum compressive stress occurs at the crown and right waist, where the right waist experiences bending and breakage due to stress from fault activity. Inside the arch, stress distribution is lower at the top and higher at the bottom, with the greatest compressive stress on the left side of the inverted arch. Overall, the secondary lining concretes comply with the safety factor requirements of tunnel. The crown and right waist, being directly impacted by the water-rich fault, sustain the maximum concrete compressive stress. Continuous moisture penetration from the fault zone to the tunnel's base rock post-construction prolong the stress stabilization period for the inverted arch, increasing the risk of floor heave during long-term operation. It is crucial to monitor the deformation of the tunnel base during operation. These results offer valuable insights for optimizing reinforcement strategies and formulating drainage plans in similar tunnel projects.
