Abstract
The utility model relates to tunnel yielding support technical field especially is a kind of supporting device for soft rock tunnel construction, including wavy surface layer, triangular hole support layer, buffer layer, steel support structure, anchor rod and fiber-optic sensor;The utility model adopts the combination design of wavy surface and triangular hole, through the unique design of tunnel structure, can effectively disperse and absorb the pressure from around tunnel, reduce the stress concentration of structure, to improve the durability and deformation resistance of tunnel, simultaneously, combined with anchor rod and steel support structure usage form " first soft later rigid " supporting system, initial period passes through wavy surface and triangular hole deformation release stress, later period passes through anchor rod reinforcement control deformation rate, have flexible yielding and structural support function simultaneously, to improve the stability and security of tunnel structure.
