| Abstract: | Application of finite element method to the simulation in excavation of cluster underground caves was discussed for the influences of excavation sequence and construction process on the stability of the caves. Based on solving problems, such as the computation of unloading and the technique for FEM simula?tion, the reasonable construction scheme was suggested for an actual project with consideration of specific con?struction conditions. This study should serve as a valuable reference for further research and engineering prac?tice. |
