Embodiment

[0019] The vertical displacement at the location of the ground fissure is large, and the section size of the standard section design cannot meet the structural deformation requirements of the six ground fissures. Therefore, it is necessary to design a large-section open-cut structure tunnel within the area affected by the ground fissure, fully considering its operation in the subway. The amount of deformation caused by the development of ground fissures during this period.

[0020] The cut-and-cut structure tunnel of this embodiment has a rectangular section, and the outline size of the tunnel section is greater than that of the standard cut-and-cut structure tunnel. If the difference is Δ, the value of Δ should be based on the ground within the design range when designing The estimated value of the maximum vertical displacement within the design life of the crack, considering a certain safety factor to determine the design value Δ.

[0021] In this embodiment, the space for s...

Abstract

This invention relates to tunnel. Specific to say it relates to adapts to large quantity stratum non-homogeneous sedimentation or the disturbed open cut tunnel. This tunnel fracture surface's configuration size is bigger than the open cut tunnel standard fracture surface's configuration size. It has at least two rectangle structures which is wholly poured to form it, the joint among it lies on the ground split. The advantages are: the structure is simple, the quality is credible, it adapts to the bigger stratum sedimentation and disturbing.

Description

technical field [0001] The invention relates to tunnels, in particular to an open-cut structure tunnel adapted to uneven settlement or displacement of a large number of strata. Background technique [0002] Ground fissure is a phenomenon that the surface rock and soil layer cracks under the action of natural factors and human factors and forms cracks of a certain length and width on the ground. Ground fissures are the result of superposition of multiple factors. In the active system of ground fissures, the main cause of formation is natural geological processes, supplemented by human factors. The activities of ground fissures have the characteristics of deformation in three-dimensional space, manifested as vertical settlement, horizontal tension and twisting. [0003] Because the activity of ground fissures is a dynamic change process, the causes, mechanisms and types are very complex, and it has obvious segmental activity characteristics according to different trends, some...
