摘要
"汶川5·12"震后修建的汶马高速鹧鸪山隧道出口端洞口位于浅埋偏压滑坡堆积体,常规方法进洞出现异常变形,通过地质补勘,采用地表注浆、锚索抗滑桩、钢管桩、抗偏压挡墙措施,左线隧道得以成功进洞;通过温度场监测,得出高原季节性冻土区温度变化规律,洞口100m长度采用径向注浆固结隧道周边1.5m范围围岩,洞口600m中心水沟埋置在冻土线下,洞口设保温出水口,控制冻融循环破坏隧道结构和排水系统,可为类似环境工程设计和施工提供借鉴。
The export of Zhegushan tunnel of Wenchuan Maerkang highway building after "5·12 Wenchuan earthquake" is at the bias of the shallow landslide,occurred abnormal deformation of conventional method,through geological prospecting,the left line tunnel is successfully entrance into the hole after use the measures of surface grouting,anchor cable anti slide pile,steel pipe pile,anti bias retaining wall,through the temperature field monitoring,it is concluded that the temperature change law of the seasonal frozen soil area,use the radial grouting to consolidate the surrounding rock of 1.5m range in the 100 m length of the tunnel,the center ditch of the portal 600 m length in the tunnel is buried under the frozen soil line,the hole using insulation outlet,control damage to the tunnel structure and drainage in the freeze-thaw cycle,which can provide reference for similar environmental engineering design and construction.
