| Abstract: | After studying the mechanical properties of anchor cable under unidirectional tensile and the difference of anchor bar, a dynamic model for the vertical vibration of prestressed anchor cable has been established. Stress wave propagation is also analyzed. The on-site test of anchor cable quality in Wangzhuang mine shows that the test on anchor cable quality with stress wave is feasible and has high value in popularization and application. |
