【 摘 要 】

A single ambient noise measurement has been found to be useful in investigating the near-surface geology in particularly for estimating site fundamental frequency. This single microtremor method is very attractive and has been successfully applied in many projects as the method is non-destructive, low cost, feasible for urban environments, fast, and deep penetration. Furthermore, this single microtremor method has been successfully applied in many projects. This paper presents the application of the single microtremor method to estimate the site fundamental frequency at a site in the historical city of Byblos, Lebanon. Pre-processing of industrial origin detection was carried out. Several durations of the measurements were investigated to obtain the most stable results. The site fundamental frequency was validated using one-dimensional site response analysis. The results are presented in this paper.
