| 摘 要： | 常吉高速公路隧道工程水文地质条件复杂,控制隧道渗流是施工中的关键技术。以青山岗分离式隧道为例,针对山区隧道裂隙岩体地下水发育的情况,以等效连续介质理论为基础,利用FLAC3D进行三维流固耦合数值分析。根据计算分析结果,指出了分离式隧道开挖前后渗透水的发生部位以及不同围岩情况需采取的支护措施,为隧道工程的安全施工提供了技术保障。

| Abstract: | The hydro-geological conditions are complicated in the separated tunnels of Changji highway,seepage control was a key in the tunnels excavation.Taking the separated tunnels engineering in Qinggangshang as example,in which groundwater are developed in the fractured rockmass,based on theory of equivalent continuous medium,the numerical simulation of seepage flow was conducted by three-dimensional fluid-solid interaction model and FLAC3D.On the basis of thre results of analysis and computation,places at which ... |
