Drilling and blasting method is often used in the construction of shallowburied Metro stations located in rock strata, and it is inevitable that vibration effect may occur to the surrounding buildings. In this paper, vibrationreducing holes are used in the blasting construction of a shallowburied station of Qingdao Metro, so as to minimize the impact on the surrounding buildings. A series of tests and monitoring have been carried out for the vibrationreducing holes, blasting vibration velocity and vibrationdamping effect. The results show that the influence on the surrounding buildings has been reduced by using vibrationreducing holes, the average vibration velocity attenuation ratio reaches 35.4%, and the safety of the surrounding buildings has been guaranteed.
