Study on Layout Scheme of Sliding Rails for Immersed Tunnel Section Prefabrication Plant

Abstract:

The cracking and deformation analysis of concrete tunnel segment in the jacking process is made by ANSYS. First, we analyzed the effect of such measures as placing a hydraulic jack between the section and rail beam sliding plane described in the four sliding rails scheme upon the cracking and deformation of segment concrete, then the influence of change in spacing of two sliding rails at the same side on the cracking and deformation of segment concrete stated in the six sliding rails scheme. Meanwhile, we made a comparison between the two layout schemes, thereby providing a basis and reference for the layout scheme of sliding rails in the practice.
