双连拱隧道基于地形条件的限制,较于普通隧道在具体的施工过程中势必会遇到各种各样的技术困难,其所采用的进洞工艺是否恰当,直接决定了双连拱隧道建设的成功与否。以察汗孟隧道为例,对连拱隧道洞口浅埋段施工工艺的具体程序及方法进行了简要说明,结合实践工作经验,重点对风积粉土地质情况下洞口浅埋段的质量、安全控制方法等方面进行了相应的分析阐述,并在此基础之上就其所存在的问题提出可行的改进措施,以此为相关隧道工程施工行业及其从业人员提供一定意义上的参考借鉴。
Double-arch tunnel based on topographic conditions, compared with ordinary tunnel construction process is bound to encounter a variety of technical difficulties, the hole is used in the process is appropriate, directly determines the double-arch tunnel construction Success or not. Taking the Chakhan-Meng tunnel as an example, the specific procedures and methods of the construction technology for the shallow-buried section of the multi-arch tunnel are briefly described. Based on the practical work experience, the emphasis is placed on the quality and safety of the shallow-buried section Control methods and other aspects of the corresponding analysis and exposition, and on this basis on the existing problems put forward feasible improvements to the relevant tunnel construction industry and its practitioners to provide some sense of reference.
