BEHAVIOURIAL STUDY OF EXPANSIVE SOILS AND ITSEFFECTONSTRUCTURES

Abstract

There has been a lot of interest in expanding soil and its influence on buildings in the past, but little research has been done to understand its behaviour and how it affects structures. No thorough analysis of expansive soil has been published in the recent decade despite many publications on its features, behaviour, stability, and consequences on buildings. This work aims to provide an overview of the properties, behaviour, stability, and impacts on structures of expansive soil. It is a review. The physics and mechanics of it have been studied and various approaches have been attempted to stabilise it up to a point. Under addition to lime and fly ash, this soil is mostly stabilised with chemicals and performs well even in the most severe situations. Although its consequences and corrective procedures on buildings have been studied, little little has been done. Research in this subject will benefit from the study's technical overview and important information for future engineers and researchers.
