Comparisons between measured and computed responses of piles adjacent to tunnelling operations Available to Purchase

Comparisons are made between the measured and computed axial and lateral responses of piles supporting a viaduct bridge in Singapore. The computed values were obtained from programs that use simplified boundary-element analyses for axial and lateral pile response, combined with input free-field ground movements obtained from approximate closed-form solutions. Parallel twin tunnels were constructed adjacent to the piles and measurements of axial force and bending moment in two of the piles that were instrumented have been reported. The agreement between measured and computed behaviour is generally good.
