Sustainability of Combined Vacuum and Surcharge Preloading
This paper presents a review of combined vacuum consolidation and surcharge preloading which is arguably more sustainable approach to soft-soil ground improvement than other strategies in reducing post-construction settlements. Vacuum consolidation has become more prevalent with technological developments in vertical drains, pumps and geosynthetics. Satisfactory vacuum pressures can be sustaine...
متن کاملEstimation of Settlement under Shallow Foundation for Different Regions in Iraq Using SAFE Software
Foundation design must satisfy limited values of settlement. Settlement is an essential criterion in the design process of shallow foundations. To calculate the settlement under different types of shallow foundations, 79 samples were taken from twenty-three sites distributed in three regions: Mosul, Baghdad and Basrah in the northern, central and southern parts of Iraq. Field and laboratory tes...
متن کاملCurrent state of the art in vacuum preloading for stabilising soft soil
In this paper the analytical solutions for radial consolidation that include time dependent surcharge loading and vacuum pressure are proposed, whilst also considering the impact of the parabolic variation of permeability in the smear zone. The use of the spectral method for multilayered soil consolidation is introduced and verified. The Elliptical Cavity Expansion Theory is used to predict the...
متن کاملEnvironmental sustainability of soft soil improvement via vacuum and surcharge preloading
Due to environmental concerns, sustainable ground improvement is considered a critical part of modern infrastructure development. Current policy on environmental sustainability often expects noise-free, chemical-free, and low carbon emission processes, while being economical. In this context, the application of prefabricated vertical drains (PVD) with vacuum preloading is regarded as one of the...
متن کاملVacuum-assisted closure: state of basic research and physiologic foundation.
A tremendous amount of research has been conducted in recent years investigating the mechanisms of action by which the application of subatmospheric pressure to wounds increases the rate of healing. Similarly, numerous studies have also been conducted examining the physiologic response of wounds to the applied subatmospheric pressure. However, many more need to be conducted. A series of basic s...
