The installation and working test performance of four full-scale instrumented driven piles and their subsequent response to twin tunnels constructed below the pile bases are described. One pair was designed to be largely friction piles and the other pair end-bearing.Their locations relative to the new tunnels were carefully chosen to optimise the understanding of pile response at varying offsets from the centre-lines. The site conditions and the greenfield response to EPBM tunnelling at the site were described in a companion paper that reported an expanding displacement field around the tunnels compared with contracting fields usually observed. Field monitoring results indicate that, during construction, zones of influence exist around tunnels (similar to those proposed by Kaalberg et al., 1999 andJacobsz et al., 2001), where the ground and piles are subjected to different degrees and senses of relative vertical displacement. Redistributions of load along the pile lengths occur as the tunnel boring machines approach, pass beneath and continue beyond the pile bases and lateral pile deflections and bending moments are also induced. Based on the results from this field study, implications for the capacity of existing piles (and design of new piles) subjected to tunnellinginduced movements are assessed for cases of expanding and contracting displacement fields.

“…Such methods have proved to be reasonably successful for the back-analysis of centrifuge and field data associated with tunnelling adjacent to piles (using centrifuge and field data reported by Loganathan et al (2000) and Pang et al (2005), respectively). Numerical analyses, such as those of Mroueh & Shahrour (2002), Lee & Ng (2005) and Cheng et al (2007), used the same centrifuge and field data for back-analysis, again with the emphasis on tunnelling adjacent to piles.…”

“…Finite-element modelling of tunnelling beneath piles has been used by a number of researchers (Mroueh & Shahrour, 2002;Yoo & Kim, 2008;Lee, 2012aLee, , 2012bLee, , 2013Yoo & Wu, 2012). Many of these studies looked at the effects of pile groups, although without high-quality case studies for comparison of the results.…”

Results from centrifuge modelling of tunnelling beneath loaded non-displacement piles in clay are presented in this paper; the principal variables were soil strength, pile loading and pile position relative to the tunnel. The details of the experimental set-up and the importance of understanding the loading history of the soil and the piles are presented in a companion paper. The subsurface pile-soil interaction was captured through particle image velocimetry; the effects of pile loading and pile position were found to have a significant impact on pile settlements. Analysis of tunnel-pile interaction through t-z load-transfer modelling of the pile-soil interface is presented using the approach described in the companion paper. The mechanisms observed in the centrifuge tests are predicted reasonably well. A significant improvement in the prediction of the induced pile loading and settlements was achieved with the inclusion of plasticity and simple power-law non-linearity for the soil.

Investigation on pile-soil-tunnel interaction due to adjacent loaded pile row by 3D FEM

Abstract. The effect of adjacent loaded pile row on the existing tunnel is analysed by 3D finite element method. The MRTA project is used as reference case in this study. The case study is divided into two cases, tunnel and pile tip located in soft clay and stiff clay, respectively. The pile diameter of 1 m and pile tip located at the elevation of tunnel crown with various number of piles within the row were considered. The analysis results are shown in terms of total soil displacement (without tunnel) and maximum tunnel deformations. Both total soil displacements and tunnel deformation increase with the number of piles and approach a maximum value when the number of piles is greater than 13 and 11 for cases tunnel in soft and stiff clay, respectively. This reveals that the tunnel deformation mechanism is primarily due to the soil displacement.
