Numerical Study on High Stiffness Segmental Joints of Shield Tunnels
Deep buried drainage shield tunnels have the characteristics of large buried depth and high inner water pressure. The load effect of high inner water pressure and large earth pressure causes the increase of bending moment and decrease of axial force in the joint section. To meet the requirements of bearing capacity and deformation of lining structures, high stiffness segmental joints (HSSJs) wi…
Experimental and Numerical Study on Longitudinal Axial Force and Deformation …
Dislocation between adjacent rings and opening of conferential joints are two typical distress of shield tunnel due to longitudinal uneven settlement. However, most existing analysis methods only considered one distress. In this study, a longitudinal deformation model of shield tunnel is proposed based on the longitudinal deformation mechanism, which takes both bending deformation and shear def…
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…
Effect of Design Parameters on Performance of Road Profilographs
Trr No. 1311 Pavement Design, Management And Performance, pp. 9-14 Road profilographs are commonly used to measure roughness of new and newly surfaced pavements. Because new pavements are usually smooth, profilographs must have measuring sensitivity, particularly in the range of profile wavelengths responsible for dynamic pavement loading applied by heavy trucks and for ride comfort. Simple an…
