Abstract
This research determines long-term shear strength of intact rock indirectly through shear creep test. The shear creep test is applied to sandstone rock sample taking from south pit Tutupan mine site of PT. Adaro Indonesia. There are two sizes of sandstone sample which are tested, first, drill core sample with 45 mm diameter that sheared through existing bedding plane, and second, square block sample that sheared through shear plane of 250 mm x 250 mm. During testing, the samples are given constant stresses, which are normal stress about 12.5% of its unconfined compressive strength, while shear stress about 81% of its shear strength under normal stress mentioned before. The shear displacement occurred during loading process is recorded as an input for creep behavior analysis. The creep behavior analysis is carried out using two approaching method which are empirical equation and rheological model. Based on the result of shear creep test the large sample has been obviously fitted to the Burger rheology model. The long-term shear strength of rock sample is then determined based on burger rheology model. Keyword: Shear creep test, long-term shear strength, large sample.
