Soft clays are prevalent in coastal areas of Australia, exhibiting low bearing capacity and considerable settlement upon loading, and must be improved as subgrades to meet the increasing demand for railway transportation soft soils beneath railway embankments are often subjected to train-induced cyclic loads generating higher excess pore water pressure (EPWP), reduced bearing capacity, and deformations under poor drainage conditions. These often lead to reduced efficiency in transportation and maintenance costs. Thus, it is important to investigate the behaviour of soft soils subjected to heavy cyclic loading and preventative actions. This paper provides a comprehensive review of the role of Prefabricated Vertical Drains (PVDs) in mitigating failures associated with railway subgrades under cyclic loading.
