Tóm tắt:

Tunnelling at shallow depth usually leads to ground settlement. The ground settlement trough over a single tunnel is generally described using Peck’s formula, which is represented by the maximum settlement Smax and the distance from the tunnel centerline to the inflexion point of the curve i. This paper introduces a nonlinear regression procedure to evaluate these two parameters of settlement troughs over a single tunnel on the basis of a numerical analysis. New relationship describing the dependence of settlement trough’s parameters on the tunnel depth, tunnel dimension, etc. is presented.
