Experiment and Analysis on influence of moisture content on the mechanical characteristics of residual soil of granite
In south China,residual soil is widely distributed and one of the most main soil in engineering construction at the coastal areas.While its mechanical characteristics are easily affected by moisture content,which is a serious threat to engineering stability and safety.In this paper,granite residual soil in a construction site of Xiamen is selected as remoulded specimens,and unconfined compressive strength test and static triaxial shear test are used,which will show the influence of moisture content (20%,23% and 26%) on the mechanical properties of specimens.As the result is analyzed,it shows that mechanical properties such as stress-strain relationship,unconfined compression strength,internal cohesive force,internal friction angle,and shear strength,are better than other specimens when the moisture content is 23%,which will be beneficial to the stability and security of engineering soil.
