Because the crane beam of the underground workshop is at the wall where the Ⅲ layer is excavated. The aim of vibration control is to control the vibration velocity to be lower than 7 cm/s. Through meassuring the several groups of prartical vibration velocity and basing on the empirical formula V=K(3Q/R) α,K and α will be solved.
In order to ensure the safety of retained dam body and grouting curtain,a reasonable and feasible criterion of blasting vibration control is proposed in the light of the experience from past projects.
On the basis of a full analysis on the results of blasting tests,the blasting parameters and blasting vibration criterion are recommended to ensure the safety of the high and steep slopes.
Based on the properties and characteristics of the structures with viscoelastic damper, this study applies a genetic algorithm to obtain a proper placement of the dampers in each story of the passively controlled building.
The results demonstrate that the proposed strategies can reduce vibration effectively, and can adapt to wind-induced vibration control of large-scale structures in the uncertain dynamic circumstance.
