The principles of bracing method: The deformations are kept minimum with the "BRACING SYSTEM” ((spraying concrete + steel mesh), floor-rock strength is protected. Similarly, BRACING SYSTEM composed of spraying concrete + rock bolt + steel mesh may be identified as a system carrying itself with the environment or the rock's carrying itself. It easily adapts to the different geological environments. It may be applied at different cut areas and very weak floor conditions. As with the deformations, floor settling are kept at minimum, and that's why it is a convenient supporting system for residential areas and shallow tunnels and HPP DAM supply tunnels.
