Analysis of Settlement Reasons and Mechanism in Immersed Tunnel

Article Preview

Abstract:

The settlement of immersed tube tunnel may be influenced by variety factors in construction, operation and loads. The factors causing the immersed tube tunnel settlement were summarized and described in-depth by cases and data. Combined the mechanism analysis with the construction process, the action time of different loads along the construction process is summarized, the consolidation characteristics and settlement mechanism of original state soil layer and base layer are analyzed. The mechanisms and variations of tidal loading, siltation and dredging disturbance, groundwater level drawdown are elaborated.
