Abstract:

Taking the Dingxi tunnel as the background, deformation rules of its typical cross-section’s surrounding loess are studied by using the finite-element software; meanwhile, by field monitoring; then the results of numerical simulation are compared with field measurement in order to get the state of stress which brought to the optimal parameters of initial support after excavation. Based on the above, some advices and techniques for initial support in the similar region, are put forward.

Key words: loess tunnel, initial support, finite-element analysis
