经十余年的不断努力，特别是2003年以后，由于国家有关部门的重视和支持，在探查预报隧道掌子面前方断层、破碎带、溶洞、暗河、地下水等方面有较大进展,结合探查实例,介绍以陆地声纳法为代表的弹性波系列方法、瞬变电磁法和探地雷达组合的成套方法技术，在断层的空间定位、探查地下水、探查溶洞、暗河等方面的理论研究成果和实测预报中取得的效果。

After more than ten years of effort, especially since 2003, great progress have been made on detection and forecast of faults, underground rivers, karst caves and ground water in tunnel construction with great supports from national administration. Based on the actual survey cases, the author introduces the complete technology of land sonar method, transient electromagnetic method and ground penetrating radar method, which have achieved good effect in theoretical researches and actual forecasts in determining the threedimensional locations of faults, survey of ground water and karst caves.
