The Kaohsiung Rapid Transit System will pass through the Southern Taiwan Science Park at Lujhu. After the system is operated, it may affect the process and quality of high-tech products in the Lujhu science-based Park. Thus, an in-site test was performed to investigate the decay of wave motions at the site of Lujhu Park. To excite the ground vibrations, an eccentric shaker and a heavy drop hammer were adopted, respectively. A series of sensitive velocity sensors were deployed at various distances to measure the ground vibrations generated. Based on the data recorded, the attenuation coefficient and soil damping related to the decay of wave motions had been deduced through spectral analyses.
