Abstract
The invention discloses a multistage tunnel shock absorption structure penetrating through an active fault. The area of the tunnel cross section of a main deformation area of a fault fracture zone of a tunnel is larger than the area of the tunnel cross section of a stable section. A tunnel lining layer is of a longitudinal variable structure and is laid in a sectioned mode, and shock absorption joints formed between adjacent lining sections are connected through flexible connectors. In the fault fracture zone and the range of influence of the fault fracture zone, a surrounding rock reinforcing circle is arranged in a grouting reinforcing mode. The space between the inner wall of the surrounding rock reinforcing circle and the tunnel lining layer is filled with a deformation adjusting layer composed of light sand. By the adoption of the multistage tunnel shock absorption structure, the safety of a tunnel structure and the stability of surrounding rocks can be improved substantially; the maximum primary stress peak value and the minimum primary stress peak value of all lining parts are decreased remarkably, and the tunnel section which is possibly damaged due to tension or pressing is remarkably reduced. After diastrophism of the lining structure happens at a diastrophism surface, the surrounding rocks can be prevented from losing stability and collapsing within a wide range, and the influences of fault diastrophism on the tunnel are reduced.
