Strength and Modulus of Weathered Rock from SPT Values In the weathered rock it is difficult to drive the split sampler to the full specified depth as in soil Hence we may estimate the strength and elastic modulus values of weathered rock by driving the spt apparatus for a fixed number of blows and find the penetration
In this study the in situ deformation moduli which were measured by borehole loading tests at basaltic rock masses located in the northeastern onshore and offshore and the northwestern onshore of Jeju Island were examined in relation to RQD and RMR The measured deformation moduli were also compared with the estimated deformation moduli from conventional empirical formulas using RQD
