2D Numerical Analysis on Influence of Embankment’s Security and Stability Caused by Shield Tunneling

Abstract:

With the increasing cases of the soft foundation embankment driven by shield tunneling, study on the influence of embankment's security and stability caused by shield tunneling becomes a research focus. The calculated model considering tunnel face pressure and friction stress between shield shell and soil is established, and the influence on embankment's stability and security caused by tunnel depth, tunnel diameter, embankment slope ratio and shield additional pressure are analyzed. The results show: when shield gradually drives to the place at the ahead of slope toe to be about 7.5m, the influence on embankment's safety stability is the most unbeneficial; when the buried depth reaches 2.5 times of the diameter, the effect can be ignored.
