摘要

Blasting and the transmission of vibration involve numerous variables which makes it impossible to predict the levels of vibrations. Therefore an effective blast design and optimization require a multitude of variables be integrated into a single instance. In prior research the existence of the strong relation between PPV and damage to structures has been well established. Besides PPV, the frequency is one of the most important factors controlling the response of structures. This paper presents a case history of Olympic Stadium renovation in Helsinki, Finland with a focus on blasting near the Olympic Stadium Tower. It will be concluded whether the current vibration criteria, measurement and approach are suitable and sufficient for near-structure blasting.
