摘要

交叉隧道开挖施工引起地层的位移会对埋置其中的既有隧道产生影响，甚至造成灾害。为此，提出了交叉隧道盾构施工引起既有隧道沉降计算的随机介质理论方法，分析了交叉隧道工程应用随机介质理论的原理及基本方程，从而建立了新建隧道盾构施工引起既有隧道沉降的随机介质模型，并探讨了计算参数的选取方法。工程实例分析表明：随机介质理论适用于计算交叉隧道盾构施工引起的既有隧道沉降变形，从而对交叉隧道安全施工具有一定的指导意义。

Abstract

The strata settlement caused by shield construction in crossing tunnels has influence on the deformation or even damage of the existing tunnel. Therefore

the stochastic medium theory is presented to calculate the existing tunnel settlement caused by shield construction in crossing tunnels

and to analyze the principles. The fundamental equations of the stochastic medium theory is applied to the crossing tunnels engineering. The stochastic medium model of the settlement of the existing tunnel resulting from shield construction in crossing tunnels is established

and the choice of parameters for calculating was discussed. The analysis for engineering example showed that it is very effective to calculate the settlement of existing tunnel caused by the shield construction in the crossing tunnels with the stochastic medium theory. The research has certain guiding significance to the shield safety construction in crossing tunnels.
