【 摘 要 】

This paper analyzes the common quasi-static calculation error sources for seismic design of underground rock structure cross-section. For the current seismic underground rock response, the finite element reaction displacement method and the finite element reaction acceleration method are used for comparative calculation to a specific geological condition. The structure of the metro station changes the applicability of seismic wave, structural stiffness, coating stiffness and structural depth to the quasi-static actuarial. It is found that the finite element response stress method is the closest to the dynamic analysis results. It is a quasi-static calculation method with high precision and applicability, which can be used for seismic response analysis of underground geotechnical structures.
