Accurately determining the effective impact radius of construction-induced vibrations, such as those caused by vibratory roadbed compaction, pile driving, and rock blasting, is essential for ensuring the safety of adjacent structures and minimizing disputes in infrastructure projects. This study experimentally investigates the propagation and attenuation of shock waves generated by blasting and pile-driving activities in typical geological conditions in Central Vietnam. Field measurements of peak particle velocity, acceleration, and noise levels were conducted using calibrated sensors in accordance with national standards (TCVN 7378 and QCVN 27:2010/BTN-MT). The experimental data were analyzed to derive empirical relationships between vibration intensity and distance from the source, enabling the estimation of safe construction distances for various structural types. The results show strong agreement between theoretical models and in-situ measurements, validating the proposed approach and offering practical guidance for infrastructure design, construction planning, and regulatory compliance.
