Heave Prediction Techniques and Design Consideration on Expansive Soils

Expansive soil has been responsible for many structural damages that result in great financial losses in many parts of the world including Saudi Arabia. Reliable prediction of ground heave is essential for the development of more effective and economical design of structures on expansive soil. Three procedures are commonly used for this purpose; oedometer test method, suction technique and empirical relationships. Available methodology for the prediction of swell potential in expansive soils and techniques proposed for quantitative analysis of heave are presented in this paper. Also, alternative soil treatment methods to minimize swell potential of expansive soils or foundation design criteria to safely accomodate ground movements are discussed herein
