More Information
Summary:The invention relates to the technical field of tunnel engineering, in particular to a tunnel lining structure penetrating through an active fault zone. Comprising a plurality of segmental linings, each segmental lining is of a multi-layer annular structure and sequentially comprises a primary support, a waterproof layer, a buffer layer and a secondary lining from outside to inside, a deformation joint is arranged between every two segmental linings, flexible connecting sections are arranged between part of the deformation joints, and the segmental linings or the flexible connecting sections are connected end to end through the deformation joints to form a first tunnel; the first tunnel passes through an active fault zone stratum, when small external seismic oscillation occurs, the multiple sections of lining structures can relatively swing along with seismic waves through the flexible connecting sections or the deformation joints so as to reduce seismic damage, and when large external seismic oscillation occ
