Straight Axial Compression Of Tiered Granite And The Discussion
Edit: Xiamen Maoshuang Stone Industry Co.,Ltd    Date: Mar 28, 2016

Based on the theory of elastic stability, determine the tensile strength of plate components due to stretching of the lower layer and instability of axial compression condition; long width 80 mm, 270~420 mm, 8~20 mm thick granite straight, rigid head or cushions into the simulation ends 5~10 mm rubber fixed and hinged uniaxial compression. Thick bar 16 mm and above takes delamination damage intensity about 40% instead of the standard samples with thickness and thin monoblock can be estimated Euler compression buckling load. Confining pressure effect on the strength of the trend, much lower standard specimen under uniaxial compression strength of granite, which stems from stretched layered compression caused by instability. Low tensile strength of rock, deep under the action of axial stress in surrounding rock of roadway possible instability and partitions appear to help break and kick drum, under plane strain State of stress analysis and the strength is not enough to confirm safety.
