Abstract

One of the method for predicting surface settlement at next tunnel-face is that convergence curve are estimated using three types of curves, advancing rate, stress release and ground characteristic based on in-situ monitoring. In this method, point-symmetrical growth curve is generally adopted as stress release curve (SRC) especially in 2-D analysis. However, it has been obvious that the SRC computed by 3-D analysis has resulted in non point-symmetrical curve. The purposes of this study are to use the Gompertz's curve as non-point symmetrical growth curve to predict the surface settlement in 2-D analysis and to verify the validity our method in comparison with field data.
