摘　　要：以复杂地质条件下高速公路隧道工程为背景,提出了一整套大断面公路隧道施工信息化方法,主要内容有:(1)基于GIS的思想开发出具有监测数据输入和输出的可视化监控系统;(2)结合隧道施工过程的模拟,提出了增量量测信息的位移反馈分析方法;(3)采用三维有限元法模拟了隧道施工的全过程;(4)采用探地雷达对隧道掘进面前方地层的变化进行了探测;(5)提出了超浅埋挖孔桩帷幕暗挖隧道施工的合理化方法,并进行了技术与经济论证。在基于GIS思想的可视化数据库的设计与运用、动态施工增量位移反演与预报、挖孔桩帷幕暗挖隧道施工技术等方面具有新意,在具体的隧道工程施工中得到了成功的应用,进一步丰富了中国隧道信息化施工的方法。With expressway tunnel under complicated geological condition taken as a background, a set of comprehensive informational techniques used for large cross-section road tunnel are presented here, which includes: (l) developing a monitoring and managing system with visual database of input and output measuring data based on GIS idea; (2) presenting a back analysis of incremental displacement combined with simulating the construction stage; (3) simulating the whole tunneling stages by use of 3D FEM; (4) exploring the strata in the advance of the excavation face of tunnel using GPR; (5) providing a suitable construction method with a retaining pile applying into shallow-buried tunnel and make technical and economical evaluation. The paper has some new ideas in the design and application of visual monitoring database on GIS, incremental displacement back analysis and prediction with staged construction, tunneling technique with retaining pile. The research results have been used in tunnel construction successfully and enriched the informational tunneling method further.
