Abstract

In this paper, author analyzed the mechanism of vibration control of composite blasting cut with high load relieving groove technology comprehensively based on the energy theory, numerical results, the measured vibration results and engineering practice. First of all, this technology can adjust and control the tower body’s stress state, increase the disintegration failure degree and speed in the tower collapsed process, then reduce the tower kinetic energy when it touchdown the ground. Secondly, it can increase the disintegration failure energy of the shock structure, and reduce the vibration wave energy. Once more, it can change the impact forms and the impact process of tower body, disperse the ground shock energy, extend the touchdown impact time, and decrease the impact strength of tower body.
