There are several studies that examine the changes in the engineering properties associated with the increase in the water content ratio of compacted ground material by microscopic soil structure. However, in previous studies, the microscopic structure of the soil a tool role for interpreting the mechanical test behavior. Therefore, the physical meaning of the microscopic structure of the soil is not clear.
In this study, the mechanical tests were performed to sandy soil were prepared by changing the water content. Furthermore, the change in deformation and strength characteristics from the mechanical tests evaluated by the suction and the coordination number obtained by X-ray CT scans. From the test results, it found that coordination number is affected the deformation and strength properties of compacted geomaterial of varying water content.
