Abstract

The invention relates to a tunnel-assembled lining structure and a tunnel across a large-scale active fault zone in a strong earthquake zone, and relates to the field of transportation infrastructureconstruction. The structure comprises an initial support layer, a spray film waterproof layer, an assembly type concrete-filled steel tube lining layer and a flexible joint; the assembly type concrete-filled steel tube lining layer is provided with a plurality of concrete-filled steel tube lining sections, each section is provided with a first steel tube sheet, a second steel tube sheet and a third steel tube sheet which are arranged from outside to inside, a first lining layer is arranged between the first steel tube sheet and the second steel tube sheet, and a second lining layer is arrangedbetween the second steel tube sheet and the third steel tube sheet. The first lining layer includes a plurality of hollow steel tubes arranged at intervals and lightweight foam concrete for filling gaps, the second lining layer comprises high compressibility concrete, and the lining sections are connected through the steel plate spring type flexible joint. The structural stability under dislocation and strong earthquakes can be ensured, and the tunnel-assembled lining structure has functions of quick installation, replacement and quick repair; the principle of stiffness matching is fully considered in the structure, and multiple measures are combined to 'lead the earthquake'.

Description

technical field [0001] The invention relates to the field of traffic infrastructure construction, in particular to an assembled lining structure for a tunnel spanning a large-scale active fault zone in a strong earthquake area and the tunnel. Background technique [0002] Tunnel engineering is generally considered to be an engineering structure with superior seismic performance. However, according to the earthquake damage of engineering structures worldwide, the earthquake damage of tunnel engineering is still relatively obvious under strong earthquake conditions. The climax of infrastructure construction is in the ascendant, and the structural design method and structural adaptability of tunnels crossing active fault areas are important issues that cannot be avoided both at home and abroad in tunnel engineering construction in high-intensity earthquake areas. For example, the total length of the Sichuan-Tibet Railway, which is in the survey and design stage, is 1,629 kilome...
