The liquefaction of soil is one of the main causes of damage caused by the earthquake,Accurate discrimination of liquefaction has become the focus of research.Therefore,the seismic liquefaction discrimination is a very important work in the regional site seismic safety evaluation.To ensure the accuracy and reliability of the evaluation results,Taking the regional seismic safety evaluation project of Plot 2 of Yangyuan Economic Development Zone,Zhangjiakou City as the research background,the methods and processes of seismic liquefaction evaluation in the seismic safety evaluation of regional sites was studied,in order to provide a scientific basis for the seismic safety evaluation work.The research results can provide a reference and guiding significance for how to carry out seismic liquefaction evaluation on regional sites.
