【摘要】 由于隧道具有地质环境复杂,基础信息匮乏的特点,因此在隧道施工前进行地质超前预报尤为重要。掌子面地质编录、超前钻孔、TSP超前探测、探地雷达探测、高密度探测、红外线探测及电磁CT探测等方法均是进行地质超前预报行之有效的方法与手段。更多还原

【Abstract】 It is important to have advanced forecast method for geologist before tunnel construction,because the tunnel has the feature of complicated geological environment and lack of basic information.Many effective methods can be taken for advanced forecast for geologist,such as,geological note for the work area,advanced borehole, TSP advanced detection,GPR detection,high density detection,infrared ray detection and electromagnetism TC detection and so on.更多还原
