摘要
在公路隧道施工中,由于勘察设计的局限性和隧道围岩地质条件的复杂多变性,施工人员对隧道掌子面前方的不良地质情况往往了解不清,隧道掘进过程中经常出现塌方、涌水等地质情况,严重影响工程进度。采用单一的地质超前预报手段往往不能达到最佳效果,采用综合快速地质预报方法进行预报,并创立了地质预报的工作流程,以白鹤隧道某出水段围岩为例进行了预报。
In construction of highway tunnel owing to limitations of prospect design and complexity of geological conditions of tunnel surrounding rock and due to the constructors often dont understand clearly poor geological circumstances around tunnel, the landslide, water welling - geological states frequently occur in tunneling, seriously affecting the engineering progress. Adopting only means of leading forecasting the geology conditions wont achieve optimum effects. The paper forecasts the geologies by synthetical high - speed methods and founds the working routine for geological forecast as example with a water - outlet section＇s surrounding rock of Baihe Tunnel.
