隧道施工过程的解析与数值结合方法

Combination of analytic and numerical methods applied in tunnel construction process

将解析与数值方法相结合，对双孔平行隧道施工过程这样一个单连通体与多连通体共存与转化的相互作用问题构造合理的半解析函数，从而使隧道施工的三维结构－介质相互作用时空问题在微机上的模拟得以实现。最后对双线盾构同向推进施工过程进行了数值模拟，旨在为今后的盾构施工提供参考。

In order to research the mutual influence of tunneling and environment, the analytic method is combined with the numerical method and a semi analytical function is produced for the double tube parallel tunnels construction with both single and multiple connected regions. Therefore, the three dimensional time and space mutual influence process of tunnels excavation can be simulated. This paper has also simulated the construction case of two shield driving in the same direction at last. The purpose of this paper is to provide a theoretical basis for shield construction.
