对不同种类土样的试验表明，控制试样侧向不变形的灵敏度高，达到了K_0固结三轴剪切试验的要求。
The test results of different kind of soil indicate that it has high sensitivity to control lateral deformation and fulfils the requirement of K0-consolidation triaxial apparatus.
另外，将原状土和循环三轴试验破坏后两种状态的土样作了对比，从微观的角度解释了土体的变形机理。
Besides, the deformation mechanism of the soil is explained from the microscopic aspect based on the contrast of the undisturbed sample and the failure sample by cyclic triaxial test.
当应力水平较高时，变形急剧增加，土样很快就出现破坏。
Soil sample is damaged quickly at high unloading stress level with deformation sharply increased.
采用在原料土中掺入微量普通硅酸盐水泥的方法制备具有不同胶结强度和初始孔隙比的结构性土样，模拟天然结构性原状土的受力变形性质。
Applying the method of mixing some ordinary portland cement into soil sample, structrued soil with different cemented strength and initial void ratio is.
