Abstract

Seismic forces significantly compromise the stability of subterranean caverns. This study focuses on the seismic support design process by using the Jiazhaerjia Cave as a case study. Initially, Prandtl's theory was employed to compute the design loads. Subsequently, optimal support mechanisms were identified through finite element simulations. The integration of the structural system with the surrounding rock mass was then analyzed to assess the stability of the structure under both seismic loads and natural conditions. The findings indicate that the proposed support structure exhibits robust seismic resistance, fulfilling the seismic mitigation requirements of the cavern. This study contributes to the framework for analyzing support schemes for similar cavern configurations.
