以武汉沙湖粉质黏土为研究对象，在不同的加荷路径和固结排水条件下，对原状土和重塑土沿3种三轴试验加荷路径的剪胀关系进行了系统整理，结果表明：1）相对于重塑土体，原状土在剪缩区（d≥0）表现出更大的剪缩量．2）而在剪胀区（d＜0），相对复杂些，若原状土与重塑土均处于OCR≤2.0的弱超固结状态，原状土和重塑土表现出大致相同的剪胀量；若原状土处于较大的超固结OCR＞2．0状态，而重塑土处于OCR≤2．0的弱超固结状态，则原状土样表现出的剪胀量明显大于重塑土样的剪胀量；3）结合试验资料，对Cam-Clay、修正的Cam-Clay、Nova Cam-Clay和Rowe等剪胀方程进行了检测．

Silty clay samples taken from Shahu of Wuhan beneath ground level 9.5 m were mainly tested , and the stress controlled triaxial shear device was used to test the natural and remoulded samples along three different loading paths under different consolidated drainage conditions respectively .The correspond-ing research results show that:1) in diltancy range with the volume decreasing (d≥0), relative to the re-moulded soil , the natural soil presents a bigger volume decrease induced by stress ratio ;2) but in diltancy range with the volume increasing (d<0), the testing observations are more complicated:when the natural and remoulded soil samples are in the state with OCR≤2.0 during triaxial shear process , the diltancy val-ues of the natural soil samples almost equal the corresponding values of the remoulded soil samples , where-as when the natural soil samples are in the state with OCR >2.0 and the remoulded soil samples with OCR≤2.0 during shearing , the diltancy values of the natural soil samples are obvious bigger than those of the remoulded soil samples;3) different types of diltancy equations such as Cam-Clay, modified Cam-Clay, Nova Cam-Clay, and Rowe, et al, are further examined and verified against the testing data .
