摘要

基于两种收缩试验的膨胀土地基变形预测方法进行了比较研究。分析表明，两种预测方法的计算结果存在较大差异，其原因在于其考虑的膨胀土地基的侧限状态不同，分别为无侧限状态和完全侧限状态下的预测结果。基于以上分析成果，并考虑膨胀土的裂隙性和实际地基的侧限状态，给出了膨胀土地基变形预测的经验公式，并将其应用于实际工程，为膨胀土地基变形的准确预测及合理处置方案的制定提供了可靠的依据。

Abstract

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.
