Abstract: This is the research to develop a new in-situ shear test effective for weathered rock as well as clay. The method is to push the layer between two parallel boreholes dy a plate of the special borehole jack and to shear a pyramid shaped mass. A trial test of the pabijast was performed at the Kamenose landslide in Osaka Prefecture, Japan. In the comparisons of the pabijast with 1) the observation of boring cores, 2) the simple shear tests using undisturbed samples taken from about the same place with the Pabijast, 3) a small landslide caused by excavation for sampling and drainage well, the Pabijast presented the values which well corresponds to the geological characteristics including the sliding surface and the ground water surface, and it gave the variation of shear strength similar to the variation of shear strength obtained from the simple shear tests. The values of the papijast (at 1 m, 2 m depth) approximately coincided with the upper yielding values of the simple shear tests which took nearly the same value with the shear strength calculated from the actual landslide.
