Use of an in-situ direct shear device on rockfill materials
A simplified in-situ direct shear test (DST) has been developed for measuring the shear strength of soils in fields. In this test, a latticed shearing frame is designed to replace the upper half of the shear box as used in the conventional direct shear box test. The latticed shearing frame is directly embedded in the ground to be tested after a construction process, and is pulled with a flexible chain while a constant dead load is applied to the sample in the shearing frame. This simplified in-situ DST has been validated by triaxial tests on samples with parallel gradations under normal stresses less than 100kPa. In this paper, this DST was further validated on the same materials rather than on the materials with parallel gradations under normal stresses up to 880kPa. In addition, this DST was performed inside fills in two applications.
