... Abstract This paper deals with the evaluation of deformability of rock mass in Himalayas by conducting in-situ tests with different methods. The deformability tests conducted by using plate jacking test, plate loading test, Goodman jack test and laboratory test show the comparison among...

... a URL at a depth of about 350 m in a sedimentary rock called the Koetoi and Wakkanai formation. The basic capabilities of RBSN modeling are demonstrated through two standard laboratory tests: splitcylinder (Brazilian) test; and uniaxial compression test.

... joints. The modeling procedure of mechanical aperture (or dilation) is precise and reliable. In addition, the proposed procedure appropriately estimates both hydraulic aperture and fluid flow rate. The conformity in the results of modeling and laboratory tests satisfactorily indicates success...

... ABSTRACT This paper describes a small laboratory test on flexural toppling failure of rock slope. This failure process involves slip between columns and tensile rupture across the colums. Gypsum columns with non-persistent cross joint were used to make a physical modeling for the slope failure...
