Checking Analysis of Lining Structural Strength in Aeolian Sand Tunnel

Abstract:

The crushing and loosening arised from the characteristics such as single particle, bad gradation, lacking of self-stability, low cohesion, loose structure and shear strength happen frequently in the aeolian sand formation. These characteristics lead to tremendous difficulty for tunnel's design and construction. Loading such as formation pressure must be undertaken by secondary lining. In this paper, relying on Shen-Mu Tunnel of Yu-Shen expressway, the strength of lining section has been checked according to internal force combination through imitating the interaction of rock and lining by applying elastic resistance. The bearing force of secondary lining in aeolian sand tunnel has been discussed through calculation by ANSYS, which plays an important directive role on the construction process and keeps the project going on well.
