EFFECT OF STRAIN RATE ON THE SHEAR STRENGTH OF ROCK PILE MATERIALS:: Geotechnical Testing Technique,Used
Delivery time: 8-12 business days (International)
Understanding creep behavior in rock piles under both dry and moist conditions will help to evaluate longterm stability of rock piles. The effect of compaction densities (1700 kg/m3 and 1850 kg/m3) on moist (8% water content) samples were also investigated for four shearing rates (0.5 mm/min, 0.05 mm/min, 0.0275 mm/min and 0.005 mm/min). Normal stresses of 160 kPa, 480 kPa and 750 kPa were used. The obtained internal friction angles versus rate of shear deformation were plotted in a semilogarithmic format and the data show a fairly consistent linear trend. For both the dry and the moist Spring Gulch rock pile materials, the shear strain rates used in this study show no major effect on the shear strength of the material, even though the friction angle and cohesion intercept were affected by the deformation rate. The internal friction angle of the rock pile materials in moist conditions decreases with increasing compaction density. In addition, cohesion increases with increasing the compaction density by keeping the water content unchanged.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
