Advancement of vacuum pressure application via prefrabricated vertical drains for stabilising soft ground

Grant

  • Linkage Projects

Abstract


  • Soft and yielding coastal clays often hamper the development of infrastructure such as commercial buildings and transportation embankments. The use of prefabricated vertical drains (PVD) with vacuum pressure can ensure sufficient pre-compression of soft clays before construction, by rapid pore pressure dissipation, increasing soil strength and minimising post-construction deformation. The main aim is to understand the intricate mechanics of PVD-vacuum systems to minimise consolidation time and eliminate excessive soil settlement and lateral movement. The outcome will be reduced construction and maintenance costs. Also, laboratory and field studies utilising computer modelling will result in improved design concepts and guidelines.
