Analytical Solution of Underneath Tunnelling-Induced Deformation of Existing …
Tunnelling underneath the existing tunnels are very common these days. It is obvious that the under-crossing tunnelling will affect and even damage the existing tunnels. An analytical method is proposed in this paper to better understand the effects of the under-crossing tunnelling on the existing tunnel. The existing tunnel is modeled as a Timoshenko beam lying on a Kerr foundation. The validi…
In-Situ Experimental Analysis of Acceleration Response of Mountain Tunnel Lin…
Resonant rubblization technology is often utilized to rehabilitate deteriorated condrete pavements. Vibrations induced by a resonant breaker would produce detrimental effects on lining structures in tunnel during rubblization construction. The in-situ experiments were carried out in Yangjiao Mountain Tunnel in Zheijiang Province, China. First, the characteristics of rubblization-induced vibrati…
Dynamic Response of Tunnel Lining to Resonance Rubblization Induced Vibration…
The resonance rubblization technology can be adopted to reconstruct old concrete pavement and eradicate reflection cracking. This method fractures pavement into fragments quickly and directly casts asphalt on fractures, shortening time cost of reconstruction. Previous studies about this technology mainly concentrated on asphalt-casting methods, and the quality, stiffness, and flatness of reco…
