摘要

基于随机介质理论研究了圆拱形断面隧道开挖对周围岩土体的影响问题，推导了隧道上覆岩土体移动及变形的计算公式，对其求解方法进行了一定的探讨，获得了该问题的半解析解，并编写了相关计算机程序。提出了随机介质变形破坏判据，并应用于隧道开挖对周围岩土环境的安全评价中。通过工程实例，理论预测结果和现场实测资料比较吻合，证明该地表移动及变形预测方法的可靠性及周围岩土环境的安全评价方法的可行性。

Abstract

Based on the stochastic medium theory

influence on the surrounding rock and soil by tunnel excavation was studied. formula for predicting movement and deformation of rock and soil mass caused by tunnelling were deduced. And especially for the tunnel with circular arch section

half analytic solution for this problem was put forward. Furthermore

a program was developed to compute the movement and deformation of the rock and soil mass resulted from excavation. The deformation failure criterion of stochastic medium for estimating the surroundings safety was provided and was applied in an engineering example

which proved that the results of the research were reasonable and significant for the tunnel safety construction.
