METHOD OF REDUCING THE SWELLING PRESSURE OF THE EXPANSIVE SOILS BY REINFORCING IT WITH THE GRANULAR PILE

摘要

The present invention relates to the method of reducing the swelling pressure of the expansive soils by reinforcing it with the granular piles. A method of reducing the swelling pressure (Sp) of the expansive soils such as clay by providing the granular pile structure in the expansive soil comprising the steps of separating type, gradation and the density of the granular pile material, installation of piles, managing spacing and arrangement of piles, identifying and preparing specified area ratio, calculating required diameter and length of piles wherein the initial moisture content of the expansive clay soil is varied and the granular pile structure has a varied relative density.
