摘　　要：剪胀性是岩土类材料的重要特性之一,1962年P.W.Rowe提出的应力—剪胀模型奠定了岩土材料剪胀性研究的理论基础和研究方法。我们经过推导,得出了粘性土应力—剪胀关系,并通过正常固结饱和粉质粘土的试验,验证了应力—剪胀关系对粘性土具有一定的适应性。Dilatancy is one of the most important characteristics of geotechnical materials. The stress-dilatancy model proposed by P. W. Rowe in 1962 was the theoretical foundation and research method about dilatancy of geotechnical materials. After deduction the stress-dilatancy relation for cohesive soil is obtained, which is proved by test study on normally consolidated satu- rated silty clays.
