Study of Sedimentation Speed and Compression Characteristics of Back-Silting Soil from Undersea Immersed Tube Tunnels

Abstract:

The immersed tube tunnels in Yangtze river delta region are affected severely by back-silting. Back-silting is difficult to control during construction and the consequences are hard to evaluate as well. In this study, sedimentation experiment was conducted incorporating back-silting soil solutions with different concentration ratios, and compression tests on the initial sedimentation layers was also conducted based on back-silting soil specimens taken from the back-silting soil sedimentary layers located in the surrounding area of Shenjiamen harbor undersea immersed tube tunnel in Zhoushan City. The undersea back-silting was assessed from the aspect of sedimentation speed and the strength of initial sedimentary layers. Results from the study are essential for further study of back-silting load and the effect of back-silting on settlement.
