分岔式的隧道施工技术目前来说,在国内和国外的使用并不是特别的广泛,因为这项技术要涉及到很多复杂的问题,比如说分离段,小净距段,连拱段等等,具有复杂的受力结构,所以会给具体的施工过程带来一定的难度,本文就这项技术在硬岩条件下的高速公路施工中的应用作一下简单的介绍。 Bifurcated tunnel construction technology Currently, the use at home and abroad is not particularly widespread, because the technology involves many complex issues, such as the separation of segments, small spacing, arch segments, etc. , Has a complex structure of the force, it will give the specific construction process a certain degree of difficulty, this paper on the application of this technology in the construction of highway under the conditions of hard rock make a brief introduction.
