Construction on cohesionless soil – A review

In India, specifically in Gujarat region like Kutch, Bhuj, Kandla large deposits of cohesionless soil are observed. Cohesionless soil is defined asthe soil which is not containing water andthe shear strain does not exist (or is negligible)between two particles. Loose and sandy material in which there is no bond between the particles is also termed as cohesionless soil. Cohesionless soil is also known as frictional soil. Cohesionless soil have lessload bearing capacity, less shear strength, less specific surface and they do not have any plasticity. Therefore, the cohesionless soil is mostly settled during earthquake and in heavy rainy season.Owing to such properties of cohesionless soil,it is very difficult to carryout construction work on such soil in a normal way.Here, need is felt to find some problems encountered during construction on cohesionless soil and methods for preventionof these problems. This paper aims at focusing the most predominant problems encountered while doing construction on such cohesionless soil and remedial measures taken for the same.
