Site Classification and Analysis in Beijing Based on Geological Factors

The paper involves the application of the surface geological method for regional site classification in Beijing. Geological maps are collected through GIS to create a relationship of classification between the geological factors of the geological maps and the site classification index of the US NEHRP code. First, the site classification of the US NEHRP is obtained, and based on the relationship of conversion, given by Chinese researchers, between the site classification of the US NEHRP and the China’s Code for Seismic Design of Buildings (GB50011-2010), the results of the site classification of Beijing are obtained based on China’s Code (GB50011-2010). Finally, based on the collected borehole data in Beijing, the results of the site classification map are verified and analyzed.
