Large scale direct shear tests on rockfill 63/180mm
Large scale direct shear tests on rockfill 63/180mm
This paper presents the results of a large-scale direct shear test campaign (1.0 m x 1.0 m x 1.2 m) performed on rockfill material, grading 63/180 mm, that was used as a foundation base for an offshore jack-up vessel. The tests were performed for normal stresses ranging between 50 kPa and 800 kPa, with the main goal of estimating the peak friction angle of the material for a normal stress of 1000 kPa. A description of the material properties is presented together with the equipment characteristics and adopted test procedures. The test results were evaluated according to the non-linear failure method proposed by De Mello (1977).
