The invention discloses a cross-fault tunnel deformation control adaptive structure which comprises a bottom deformation active control system and an upper deformation adaptive structure. According to the bottom deformation active control system, a plurality of rigid concrete bottom plates are hinged in the longitudinal direction through flexible materials to form a concrete bottom plate foundation capable of adapting to longitudinal deformation; a plurality of electric hydraulic jacks are uniformly arranged on the concrete bottom plate; a traveling crane bottom plate is mounted at the tops of the electric hydraulic jacks; meanwhile, a plurality of electronic displacement meters are mounted between the concrete bottom plate and the traveling crane bottom plate; according to the upper deformation adaptive structure, the outer side of the tunnel lining is filled with a compressible asphalt-concrete material, a deformation gap is reserved between the tunnel lining and the asphalt-concrete material, and a plurality of electronic displacement meters are arranged in the deformation gap. Displacement data of a fault under the long-term creep action are monitored in real time, and then the height of the bottom of the tunnel is adjusted to enable the displacement data to be consistent in the longitudinal horizontal direction; longitudinal non-uniform deformation of the tunnel crossing the active fault is avoided, and safety and stability of the tunnel structure and smoothness of a line are guaranteed.
本发明公开了一种跨断层隧道变形控制自适应结构，包括底部变形主动控制系统和上部变形适应结构；底部变形主动控制系统为：若干刚性混凝土底板通过柔性材料沿纵向铰接形成可适应纵向变形的混凝土底板基础；混凝土底板上均匀设置若干电动液压千斤顶，电动液压千斤顶顶部安装行车底板；同时，混凝土底板和行车底板之间安装若干电子位移计；上部变形适应结构为：在隧道衬砌外侧填充可压缩的沥青‑混凝土材料，隧道衬砌和沥青‑混凝土材料之间预留变形空隙，变形空隙中设置若干电子位移计。本发明通过实时监测断层长期蠕滑作用下的位移数据，然后调整隧道底部高低，使其在纵向水平一致；避免了跨活动断层隧道的纵向不均匀变形，保证了隧道结构的安全稳定和线路的平顺性。
