Utilizing rock brittleness for estimating TBM penetration rate in rocks

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The brittleness is one of the most crucial rock parameters for mechanical excavation in rock mass environment. In present, there is no agreement in rock mechanics society to direct measurement of the brittleness; however, several approaches using rock strengths have been introduced to indirectly determine the brittleness. Further, punch penetration test (PPT) is being used for directly measuring the rock brittleness in recent. This paper review the rock brittleness index computed from PPT and also examines the collected data from various tunnel projects to estimate the tunnel boring machine (TBM) performance as a function of introduced brittleness index. It is concluded that the test can be used for both measuring the rock brittleness and estimating the TBM performance with some constrains.
