Evaluation of Soil Mechanics Laboratory Equipment. Report no. 9. Comparison of Controlled-Stress and Controlled-Strain Direct Shear Tests on Two Compacted Soils.
Abstract
Consolidated-drained direct shear (S) tests were made by the controlled-stress and controlled-strain methods using compacted samples of two types of soil. The results indicate that peak shear strengths determined by the two methods are in reasonable agreement. The controlled-strain method has the following advantages: (a) it permits determination of ultimate shear strengths and better control of the rate of deformation, and (b) the application of shear stress is automatic and the method is more adaptable to electronic recording of stress and deformation data.
