Abstract
SR-2 type soil resistance measuring instruments have been used from about 1965 in Japan as measuring tools for field use to measure soil dynamic values. But the SR-2 type method for measuring soil shearing resistance, which has the outer diameter of 100 mm, the inner diameter of 60 mm and the height of vanes of 10 mm and takes the half of shearing torque as the shearing resistance in the bottom of annulus, neglects the side effect. Therefore, various discussions have been done. This study made it clear that the effect of annular inner side was extremely small because the soil was pushed up and broken out and the effect of outer side were fairly large and shearing was brought about. This side effect appeared larger in cohesion (the ratio of 1.83 ± 0.48 to the control) than in internal friction angle. And also, this study presents such method for improving without harming the feature of SR-2 type as measuring tools for field use as that it is most suitable to cut away previously the outer side of annulus with a cutter knife.
