The Research on Displacement and Stress Variation Rule of Surrounding Rock in the Shallow Buried Tunnel Excavation
Translated Abstract
Using finite element analysis software MIDAS/GTS to numerically simulate the excavation process of Huangdongpo shallow buried tunnel, analyze the surrounding rock deformation and stress distribution of the shallow buried tunnel. At the same time, combined with the field monitoring data, finally it is concluded that the maximum displacement and the maximum stress of surrounding rock appeared in the vault and the arch waist position respectively, so it is important to control the subsidence of the tunnel vault and alleviate the stress concentration of the arch waist in the shallow buried tunnel construction, which requires the necessary support in advance, the primary support in a timely manner and the close monitoring of the danger zone to ensure construction security.
