【 摘 要 】

By summarizing the research results of the site effect coefficient and topographic effect coefficient of ground motion peak acceleration, we analyzed the ground motion site effect and topographic effect and concluded that the relationship between site effect and topographic effect was wane and wax and gradually transition. The amplification factor of the peak acceleration of the surface can be calculated by multiplying the site effect coefficient and the topographic effect coefficient. The article proposes to study the site effect coefficient and the topographic effect coefficient in two ways and obtain the function expression. In the introduction of Vs30, the calculation method of the limits of two effect of Vs30 as the parameter is also proposed. Through the above methods, accurate ground motion peak acceleration can be obtained, which provides support for seismic design, ground motion attenuation relationship research and seismic geological disaster prevention.
