Abstract:

The study on the deformation of the central diaphragms of tunnels constructed by means of CRD method is inadequate in China. On basis of the monitoring results of Xiang'an subsea tunnel in Xiamen, China, the authors analyze on the deformation rules of the central diaphragms of tunnels constructed by means of CRD method in the paper, which provides basis for the safe construction of the tunnel and can provide reference for similar works in the future.
