ABSTRACT Li, L.-B.; Zhang, J.-H., and Zhong, D.-W., 2019. Study on blasting vibration control technology in coastal oil depot area. In: Gong, D.; Zhu, H., and Liu, R. (eds.), Selected Topics in Coastal Research: Engineering, Industry, Economy, and Sustainable Development. Journal of Coastal Research, Special Issue No. 94, pp. 285–290. Coconut Creek (Florida), ISSN 0749-0208. According to the actual engineering, the combination of theoretical analysis, numerical simulation and on-site blasting vibration velocity measurement is used to discuss the blasting vibration law of the Coastal oil depot in different working conditions. The results show that the damping grooves have obvious effects on reducing blasting vibration. Under the same constant excavation area and depth, the best damping effect is obtained when damping grooves are set close to the blasting source. In addition, the damping effect of the two rows of damping grooves is better than the single row of damping grooves, and within a certain range, the damping effect rises with the increase in the gap between the two rows of damping grooves.
