Abstract

In this paper, a three-dimensional elasto-plastic numerical simulation was conducted to investigate the effects of an advancing open face tunnel excavation on an existing loaded pile. The computed results are compared with measurements from a centrifuge model test. A significant zone of influence can be identified one tunnel diameter ahead and one behind the tunnel excavation face. Due to an additional settlement of the pile induced due to tunnelling, the soil resistance factor of safety (FOS) for the pile can be regarded as decreasing from 3.0 to 1.5. However, the tunnel excavation did not significantly affect the existing bending moment and axial load distributions within the pile.
