Abstract

This study deals with the comparative investigation on various classification systems for sedimentary rocks, approximately 4,5 km long of the Highway Speed Railways Tunnel No. 6 Jakarta - Bandung. The results of extensive geotechnical explorations and field measurements were applied to obtain the rock mass classification systems such as Rock Mass Rating (RMR), Q-system (Q), and Rock Mass index (RMi) for a wide range of sedimentary rocks. A set of systems inter-relationship is proposed. So, it is proposed to find relations between any pairs of systems that both of them consider or not consider these parameters. The relations are proposed for a wide range of sedimentary rocks and can be applied for similar geological environments.
