“…This behaviour of flow bands under dynamic loading was observed during all experiment. These observed results are similar to the results reported by Ahola et al (1996). The reason for the phase shift between shear stress and shear displacement is associated with chatter of the joint surface and vibrations of the apparatus as reported already by Ahola et al (1996).…”

“…These observed results are similar to the results reported by Ahola et al (1996). The reason for the phase shift between shear stress and shear displacement is associated with chatter of the joint surface and vibrations of the apparatus as reported already by Ahola et al (1996). The most important issue in many problems of discontinuities under dynamic loads is the relationship between shear strength and unit strain.…”

Stability and deformation analyses of geotechnical projects such as tunnels, underground excavations and rock slopes require reliable data about the behavior of discontinuities (joints, fractures, bedding planes and etc.). Therefore, shear box tests are widely used in rock mechanics applications. In this study, several static and dynamic shear box tests were carried out both over flow bands of the andesites which cover a large area in the northern part of Izmir Bay. Shear box tests were conducted under both static and dynamic conditions on rectangular planes with a dimension of 400 x 200 mm. As a result of these tests, normal displacement-normal stress, shearing displacement-shearing stress and normal displacement-shear strength correlations were obtained. Also, peak and residual shear strength values, base friction angle and residual friction angle were found and the results were interpreted. Thus, the shear strength properties of the flow band structures can be given with more accuracy. Based on the new findings, more realistic solutions will be obtained in numerical analyses and simulation models aiming at determining the stability of underground excavations and engineering projects on the ground surface will be more reliable.
