Experimental Study on Anchoring Mechanism of Pre-Stressed Anchor Cable by FLAC3D Numerical Simulation

For questing anchoring mechanism and meeting anchor cable engineering´s requirement of construction and design, this article research on anchoring mechanism of anchor cable with FLAC^3D simulation software. The result indicates that rock mass around anchor pier forms a compression stress concentrating region, and rock mass around bonded section appear tensile stress and compression stress concentration area, and both overlapping zone. The value of axis force is bigger at the top of the bonded section, and the force rapidly attenuates along bonded section to the end of anchor cable. Moreover, the curve of shear stress basically presents exponential function distribution along bonded section.
