Laboratory and theoretical investigation of soft clay behaviour under cyclic loading stabilised by prefrabricated vertical drains

Abstract


  • Soft and yielding coastal clays often hamper the development of transportation infrastructure including embankments that are subjected to cyclic loads. The use of prefabricated vertical drains (PVD) can ensure sufficient drainage of soft clays by rapid pore pressure dissipation, thereby increasing the soil strength and minimising post-construction deformation. The main aim is to understand the intricate behaviour of soft soil under cyclic loading stabilised by PVD to control excess pore pressure generation and associated settlement and lateral soil movement. The outcome will be reduced construction and maintenance costs. Laboratory and field studies utilising computer modelling will result in improved design concepts and guidelines.
