Yielding component for large deformation control of surrounding rock of high ground stress soft rock tunnel

Abstract

The utility model discloses a yielding component for large deformation control of surrounding rock of a high ground stress soft rock tunnel. The yielding component comprises two parallel connecting plates, a first V-shaped plate and a second V-shaped plate, wherein the first V-shaped plate and the second V-shaped plate are positioned between the two connecting plates; the first V-shaped plate and the second V-shaped plate are crossed with each other; a connecting line of the top end of the first V-shaped plate and the top end of the second V-shaped plate is perpendicular to the connecting plate; and the bottom ends of the first V-shaped plate and the second V-shaped plate are fixedly connected with the corresponding connecting plates. The utility model aims to provide the yielding component for controlling the large deformation of the surrounding rock of the high-crustal-stress soft rock tunnel, so as to solve the problem of controlling the deformation of the surrounding rock of the high-crustal-stress soft rock tunnel in the prior art, and achieve the purposes of absorbing crustal stress, releasing energy and protecting a supporting structure.
