摘要： A composite support system based on a steel-concrete (concrete-filled steel tube) support and a shotcrete arch includes an anchor mesh layer provided on an inner wall of a roadway. A flexible compressible layer is provided on the outer side of the anchor mesh layer; a support frame is erected on the outer side of the flexible compressible layer; reinforcement meshes are respectively arranged on an inner side and an outer side of the support frame; the support frame and the reinforcement meshes form a framework to construct an arch spray layer; the reinforcement meshes and the support frame are embedded into an arch structure to form a rigid layer; the flexible compressible layer is provided between the rigid layer and the anchor spray layer. When the flexible compressible layer is compressed, the flexible compressible layer is deformed toward a reserved deformation space for a yielding purpose.
