In our previous paper1) the cyclic shear tests on sand are performed using Kjellman's type simple shear box, fixed on a shaking table. The tests are performed under a vertical stress(σ'z) of 49.4kPa. From the test results, the equation calculating the principal stresses induced in sand is obtained. Furthermore it is found that the internal friction angle of sand decreases 2.5°with increasing a seismic coefficient kh by 0.1. In this paper to confirm this result the same tests as previous ones are carried out under σ'z=29.8 kPa. As a result it was found that the result of this investigation is the same as that for the previous one. Therefore this test results are presented in a generalized form. キーワード（英）： - 記事区分： - 区分 　　　　論文集
