Tunnel’s Deformation and Control Technology

Tunnel’s Deformation and Control Technology

After excavation of tunnel, stress from initial stress field will be relieved, which will inevitably arouse deformation of various forms, such as arch crown subsidence, surrounding rocks from two sides squeezing in, bottom parts plumping up and tunnel face squeezing out, etc. Then it will cause slack, even instability and collapse. So the purpose of […]
