Soil sample undisturbed

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.

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。

The quality of undisturbed soil sample plays an important part in geotechnical investigation.

原状土样质量在工程勘察中是极为重要的。

The grain size analysis and microstructure observation of the undisturbed soil samples from both sides of the road were made, and the fractal theory was used to analyse the soil sample.

对两侧原状土样进行粒度成分测试和微观结构观测，并利用分形理论进行分析。
