Application of Schmidt rebound number for estimating rock strength under specific geological conditions
A literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (UCS) of rocks based on the Schmidt hammer rebound number (N) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. This is attributed to the fact that in most cases one formula is used for all types of rocks, altho...
متن کاملShear Strength of Rock Joints Based on Quantified Surface Description
One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

متن کاملevaluation of rock mass deformability
One of the most important effective parameters in design of engineering structures is deformability of rock mass. Benchmark of rock mass deformability is the deformation modulus that directly or indirectly obtained. Since the determination of rock mass deformation modulus indirect method by in-situ tests is time-consuming, costly and difficult from executive operations aspect, so it’s correctly...
متن کاملEstimating rock mass elastic modulus from seismic resonance measurements
Measuring the elastic modulus of in-situ rock masses over scales of tens of meters remains an important challenge in experimental rock mechanics. We present a new approach using ambient resonance measurements of freestanding rock masses to identify vibrational modes, which are then matched with numerical models implementing bulk, globally representative material properties. The result is an exp...
