摘要
依托青海高海拔寒区姜路岭隧道工程,对防寒泄水洞的施工特点以及和主洞的相互影响进行了分析探讨,利用有限元分析软件对防寒泄水洞进行数值模拟,得出了超前100m开挖防寒泄水洞对隧道主洞无沉降影响的结论。
Taking Jiangluling Tunnel in Qinghai as an example, the construction features of cold-proof spillway tunnel and the influence on the main tunnel are analyzed and discussed, and the finite element analysis saftware is used for the numerical simulation of the tunnel, thereby to come to get the conclusion that there would be no influence of settlement on the main tunnel when advancedly excavating the cold-proof spillway tunnel for 100 m.
