This paper assumes that the volume of the subsurface settlement troughs due to tunneling is equal to the ground loss and the shape of the troughs can still be represented by a Gaussian distribution . It is firstly presented by this paper that researchers can study the width parameters of the settlement troughs with different depths through analyzing the settlements above the center line of the tunnel
and then a regression equation used to calculate the width parameters of the settlement troughs with different depths can be derived; as a result
the settlement of every point above the tunnel due to tunneling can be attained. The applicability of this method has been demonstrated by the calculation of actual projects.
