摘要

假定由于隧道开挖在地表以下土层所形成的沉降槽的体积等于地层损失以及各土层沉降槽曲线仍可用正态分布函数表示。在此假定下，首次提出可以通过对隧道中心线以上土体的沉降值的分析，研究不同深度土层沉降槽曲线宽度系数，并且通过回归分析，提出用于计算不同深度土层沉降槽曲线宽度系数的公式，为计算隧道开挖引起的地表以下土体任一点的竖向沉降提供了一种有效方法，通过工程实例的计算证明了该方法的适用性。

Abstract

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.
