Soil Testing With The Consolidation And Direct Shearing And California Bearing Ratio
Application
The foundation soil base will give loading support for any building structure and bridges. So the soil features of this area will affect whether this place is suitable for the some large constructions. Then the soil testing work is necessary and will give the direct support before the area choice. For the soil testing work, the basic testing will include compression testing by Consolidation apparatus, resisting shear strength testing by Strain controlled Direct Shear Apparatus, moisture content testing by Liquid and Plastic Limit Tester, California Bearing Ratio testing by CBR tester, and so on.
