英文摘要	The inversion of site velocity structure using Horizontal-to-Vertical Spectral Ratio (HVSR) is a rapidly developing research field. The essence of this inversion is a global optimization problem of model-space search for soil structure. When the complexity of the model-space search increases, the commonly used search algorithm is slow to converge and the calculation efficiency is low. To solve these problems, a hybrid global optimization algorithm combining genetic and simulated annealing algorithm is proposed and validated by a theoretical model and observation data of the vertical array, respectively. The results show that by this algorithm permits to enhance the convergence of the Monte Carlo method, avoid premature convergence of the genetic algorithm and improve the search inefficiency of the simulated annealing algorithm and achieve good inversion results. Besides, this paper also discusses the applicability of S-wave HVSRs of accelerograms recorded by a single station for inversion of site velocity structure. These provide an accurate and high efficient inversion method for determining the site velocity structure based on observation of a single station.
