Numerical analyses for the design of helical piles for trackbed stabilisation
Numerical analyses for the design of helical piles for trackbed stabilisation
The presence of compressible soil beneath a rail track can cause recurrent defects and high maintenance costs. This paper describes the numerical analyses carried out for the design of the trackbed stabilisation of a rail embankment over peat through installation of small diameter helical steel piles. A combination of axisymmetric and 2D plane strain finite element analyses were carried out to assess the improvement to the trackbed stiffness offered by the proposed intervention. Trackbed deflection monitoring was also considered for the calibration of the numerical model.
