International Journal of Scientific & Engineering Research, Volume 6, Issue 12, December-2015 217 ISSN 2229-5518 IJSER 2015 Soil Improvement Techniques Gaafer,Manar, Bassioni,Hesham, Mostafa,Ta r eq Abstract Soil at a construction site may not always be totally suitable for supporting structures in its natural state. In such a case, the soil needs to be improved to increase its bearing capacity and decrease the expected settlement. This paper gives an overview of Techniques that are commonly used to improve the performance of saturated clayey soil in situ, its functions, methods of installation, the applicable soil types and cost of those Techniques .
clay layer by using rotary drilling, continuous flight auger or driving down hollow mandrels into the soil. The holes are then filled with sand.When a surcharge is applied at the ground surface, the pore water pressure in the clay will increase, and it will be dissipated by drainage in both vertical and horizontal directions. Hence the ...
