Problems solved by technology

[0005] The large-deformation bolts (cables) and telescopic steel frames of the constant group are mainly used in mine roadways, not suitable for tunnel engineering, because they are independent working systems, and sprayed concrete is required for initial support after excavation in tunnels Yes, the variability of the concrete structure is limited. Once the primary support forms a closed concrete structure, the constant set of large-deformation anchors (cables) and telescopic steel frames lose their setting significance

Abstract

The invention provides a large-stroke combined damper utilizing the post-peak performance of materials. The large-stroke combined damper comprises a circumferential damper and a radial damper, and the circumferential damper and the radial damper are arrayed around the inner side of a tunnel to form a ring; the circumferential damper is fixedly installed in the tunnel, and the deformation direction is in the circumferential direction of the tunnel; the radial damper is fixedly installed in the tunnel, and the deformation direction is in the radial direction of the tunnel; the circumferential damper is positioned on the inner side of the radial damper. Supporting and deformation can not only be provided in the circumferential direction of the tunnel, but also can be provided in the radial direction of the tunnel, stress of the tunnel is effectively released, so that the tunnel structure is more stable and reliable.

Description

technical field [0001] The invention relates to the field of tunnel engineering, in particular to a large-stroke combined damper utilizing the after-peak performance of materials. Background technique [0002] Our country is in a period of rapid development of tunnel engineering construction, and a large number of surrounding rock stability issues are involved in the fields of transportation, mining, and water conservancy. Large deformation problems are often encountered when the tunnel structure passes through weak and broken surrounding rock strata, which is characterized by continuous large deformation of the surrounding rock of the tunnel, peeling, falling, and crushing of the primary support concrete, and twisting of the steel frame, which makes construction difficult and difficult. The progress is slow, the disease control is difficult, the construction risk is increased, and the construction cost is soaring. [0003] When large deformation is encountered, the existin...
