Paper presented at the ISRM International Symposium - 10th Asian Rock Mechanics Symposium, October 29–November 3, 2018
Paper Number: ISRM-ARMS10-2018-057
... Abstract In the current practice on rock mass classification in Singapore, the weathering grade is commonly used to determine rock mass classes with some consideration of strengths and discontinuities based on visual examination of rock cores. By application of Geological Strength Index (GSI...

Paper presented at the ISRM International Symposium - 8th Asian Rock Mechanics Symposium, October 14–16, 2014
Paper Number: ISRM-ARMS8-2014-070
..., the knocking ball tests are applied in two practices, one is to evaluate aggregate quality and the other is to determine the rock mass classification. The result of the first assignment shows that the knocking ball test is more useful and appropriate than the Schmidt impacthammer to obtain reliable elastic...

Paper presented at the ISRM Regional Symposium - 7th Asian Rock Mechanics Symposium, October 15–19, 2012
Paper Number: ISRM-ARMS7-2012-076
... rock mass classifications such as RMR and Q-system. The authors estimate rock mass properties of Ryukyu limestone, which are quite important for the design of engineering structures as well as assessing the stability of natural rock structures such as caves and cliffs. The unified formula proposed...

... are regarded as a tool for design of tunnel. Empirical methods have been extensively used in rock mass classification. In most of the projects, the rock mass classification is being considered as the only criteria for designing the complex underground structures. Based on the recorded information...

... tunnels, penstock pipes.Using the rock mass classifications by RMR and Q systems, the fractured rock masses along the penstock tunnels are divided into two critical sections as I and II. By considering the rock mass classifications, 3D numerical solution proposed to specify temporary and permanent support...

Paper presented at the ISRM International Symposium - 6th Asian Rock Mechanics Symposium, October 23–27, 2010
Paper Number: ISRM-ARMS6-2010-112
.... The rock support consisting of rock bolts and shotcrete was designed based on the rock mass classification and 3D numerical modeling of entire power house complex. Each stage was supported before commencing next stage. The cavern was dry. No seepage of water was encountered. However, holes were drilled...
