Abstract :
Permeability and shear strength are very important properties of a soil which are affected by grain size of soil particles. For the improvement of soft soil sometimes sand pile are used. The main objective is to investigate which type of sand is more suitable for sand pile economically. in this project, an attempt is made to relate permeability and frictional angle with the properties of grain size of soil such as effective size (d10), mean particle size etc. the properties of grain size can be found out from gradation curve. The results of coefficient of permeability vary from 1× 10-3 to 15× 10-3. The permeability increased significantly with the increase of mean particle size and effective size of sand. Frictional angle increased with the increase of permeability of soil but the variation is very insignificant. Shear strength also increased with the increase of mean particle size but the variation is also insignificant in this case. as the changes of value of frictional angle is neg
