摘要
随着城市的不断发展,城市的隧道建设越来越多,在新建隧道近距离下穿施工时一定会对既有隧道造成影响。正确的分析、预测既有隧道变形特点便成了现代浅埋暗挖法下穿施工中的一项重要工作。在现代的预测工作中,一般采用Peck公式,这种方法最简便,应用也非常广泛,对于近接工程设计和施工有很好的帮助作用。
With the continuous development of the city, the construction of the city＇s tunnels is more and more, and it will certainly affect the existing tunnels when the new tunnels are under construction. The correct analysis and prediction of both the characteristics of the tunnel deformation has become an important work in the construction of modem shallow buried excavation. In the modem prediction work, the general use of Peck formula, this method is the most simple, and the application is also very wide, for the proximity of enineerint, design and construction of averv good heln.
