Settlement restraint is necessary for concrete slab track on soft soil to guarantee vehicle running stability and maintenance of track systems. Although the construction of some bridges or the replacement of soft soil is able to be solution for the settlement of soft soil, these methods are economically infeasible. Recently concrete deck on pile system has been applied to concrete slab track as an alternative method for restraining the settlement of soft soil in Europe and China. Some advantages of concrete deck on pile system are structural stability, the relative simplicity of design/construction and an economical system. In this paper, the field applications of concrete deck on pile system in Europe and China were investigated and optimal section of concrete deck on pile system being able to apply to a domestic soft soil was reviewed.
