Abstract

Shear strength parameters such as friction angle of discontinuity surfaces of rock are among the essential data for the design of rock engineering structures like underground excavation and cut slopes. Constant normal load direct shear test has been employed on artificially sawn surfaces of fresh and slightly weathered granite to determine the basic friction angle of the discontinuity plane surfaces. The granite samples were collected from Kajang Rock Quarry, Semenyih, Ulu Langat, Selangor, Kajang Silk Highway (km 14.6), Selangor and Pos Selim-Kampung Raja road (km 30-29), Cameron Highland, Pahang/Perak and JKR Quarry Bukit Penggorak, Kuantan, Pahang. A total of 84 direct shear tests were carried out, comprising 65 and 19 tests on fresh and slightly weathered granite, respectively. For fresh granite, the basic friction angle is 42° ± 0.6° with standard deviation of 2.26 and coefficient of determination, R 2of 0.98. For slightly weathered granite, the basic friction angle is 38° ±1.9° with standard deviation of 3.99 and coefficient of determination, R 2 of 0.97. These values are considerably higher than the often assumed value of 30°-35° for fresh granite.
