Computation of Predicted Heave
The calculation of predicted heave should be the first step in the design of shallow and deep foundations or other ground supported structures, such as slab‐on‐grade floors and pavements. The various methods for calculating heave can be grouped into three main categories. These include oedometer methods, soil suction methods, and empirical methods. This chapter discusses some of the more rigorous methods. To predict the amount of heave at a given time, such as the design life, the progression of heave must be considered. One method that has been used to predict the progression of heave is an observational method based on periodic elevation surveys and heave measurements, and extension of that database into the future by means of curve fitting. Another method is to analyze the migration of water in the zone of potential heave, and relate free‐field heave to water content changes. The chapter discusses both these methods.
