摘要： A combined type flexible glass net system used for protection against full-particle falling rocks on plank roads in scenic spots includes a supporting layer, an intercepting throwing layer and a flexible glass net isolating layer, wherein the supporting layer is longitudinally arranged above a protective area along a mountain, and includes a supporting steel frame and an oscillating type supporting rod; the intercepting throwing layer is supported on the supporting layer, and includes metal meshes, an along-cross-slope lower connecting rope, an along-cross-slope upper connecting rope, an along-slope connecting rope and a reinforcing rope; and the flexible glass net isolating layer includes glass plates, glass net supporting cables and a hoop type hinged piece, wherein the glass plates are connected to the glass net supporting cables through the hoop type hinged piece, and the glass net supporting cables are hung below the supporting steel frame.

摘要： A two-stage energy dissipation type shed tunnel support structure connected by a principle of Dougong and a design method thereof are provided. The two-stage energy dissipation type shed tunnel support structure includes a Dougong joint domain, crossbeams and columns. The Dougong joint domain includes section steel members, wavy-wall cylindrical elastoplastic buffers, U-shaped sliding connecting troughs and high-strength bolts. Multiple layers of the section steel members are orthogonally stacked to form a Dougong shape, the wavy-wall cylindrical elastoplastic buffers are arranged between adjacent layers of the section steel members, and the U-shaped sliding connecting troughs are arranged at upper and lower ends of the wavy-wall cylindrical elastoplastic buffers, which realizes a connection between the wavy-wall cylindrical elastoplastic buffers and a section steel in two orthogonal directions. Under an impact of small energy rockfalls, an elastic deformation of the Dougong joint domain is used to achieve a buffering.
