Two prediction methods of ground heave in expansive soil foundation based on shrinkage test are introduced; and the comparison research of prediction result is carried out. The analysis indicates that the calculation results of the two prediction methods exist bigger difference for different shrinkage indexes is adopted as calculation parameter. The prediction values of the two methods respectively correspond the lateral unconfined state and complete lateral confined state. Considering the fissure characteristic of expansive soil and the actual lateral confinement state of the foundation
an empirical formula is developed to calculate the ground heave. The suggested method enhances the accuracy of heave prediction of expansive soil foundation
it has significant meaning to the treatment scheme design of expansive soil grounds.
