Abstract

This paper proposed an analytical method to study the mechanical behaviours of the existing tunnel due to new tunnelling below. The coefficient of subgrade reaction of the existing tunnel can be considered as a variation instead of a constant. The resultant deflections of the existing tunnel can be calculated by a superimposed method. The proposed method is verified by the finite element method. The influences of the input parameters on the deflection of the existing tunnel are studied. Based on a below-crossing project in Beijing, the results obtained by our method match well with the monitoring data.

由于新隧道建设，现有隧道的表现如下

本文提出了一种新的分析方法来研究地下隧道开挖对既有隧道力学性能的影响。既有隧道路基反力系数可以看作是一个变量而不是常数。现有隧道的综合挠度可以用叠加法计算。用有限元法对所提方法进行了验证。研究了输入参数对既有隧道挠度的影响。以北京某下交工程为例，所得结果与监测数据吻合较好。

期刊介绍： The use of computers is firmly established in geotechnical engineering and continues to grow rapidly in both engineering practice and academe. The development of advanced numerical techniques and constitutive modeling, in conjunction with rapid developments in computer hardware, enables problems to be tackled that were unthinkable even a few years ago. Computers and Geotechnics provides an up-to-date reference for engineers and researchers engaged in computer aided analysis and research in geotechnical engineering. The journal is intended for an expeditious dissemination of advanced computer applications across a broad range of geotechnical topics. Contributions on advances in numerical algorithms, computer implementation of new constitutive models and probabilistic methods are especially encouraged.
