The earthquake resistance research of underground structures is and geotechnical engineering. A summary of the research methods in und very important in earthquake engineering erground structures is presented. The simplified method, refined finite element method and model shaking table tests for underground structures are introduced respectively. The scope of application for the simplified method is analyzed;some problems needing attention are suggested in the finite element method;and some problems needing improvement in shaking table tests are presented. Finally, some problems in earthquake resistance of underground structures which need further investigation are suggested.
