查询词典 finite element method

Combining the actual rockburst status after excavation, based on the previous research data in the earlier stage, the character of the tectonic stress in Cangling Tunnel is studied. Finite element method is adopted to simulate the site excavation steps. At the same time, the tectonic stress is changed on the boundary of the model to simulate the actual rockburst areas; and the most proximal area's value is adopted to decide the section tectonic stress. Then, other sections' values are revised.
