The shear failure of foundations and earth structures with the long length is the plane strain shear failure. The paper describes briefly the plane strain shear test carried out in our laboratory. Generally, the techniques of the plane strain shear test are torelably difficult and the apparatus is complex. We have made the simple apparatus of the plane strain shear test in the light of the apparatus developed by Dr. Duncan J. M. at University of California. The test specimen is the rectangular solid with 3.5cm in width, 7.5cm in length and 8.0cm in height. The end clamp is set in order to arrest the displacement of the direction of length. The shear strengths of three kinds of dry sand in plane strain shear test are compared with strengths measured in triaxial test at the same initial density and the pore water pressure produced during the test of saturated sand in plane strain shear test is measured. These experimental results were satisfactory.
