摘要：

Experimental data from unreinforced direct shear tests on sand are presented to show the influence of the boundary conditions on the test measurements. The data and the theoretical considerations of the loading in the test show that a symmetrical direct shear test arrangement is preferable. A new method of analysis for the direct shear test is introduced based on the relationship between the sand shearing resistance and dilatancy. The symmetrical direct shear test is an effective method for the measurement of the plane strain and direct shear angles of friction for sand. A simple modification for the standard laboratory direct shear apparatus and suggestions for the analysis of standard test data are recommended.
