Overview of tunnel geological advanced prediction in China

SONG Xian-hai,GU Han-ming,Xiao bo-xun(Institute of Geophysics and Geomatics,China University of Geosciences,Wuhan 430074,China)  
Tunnel geological advanced prediction is not only fundamental in tunnel excavating but also a difficult problem to the engineering geophysical circles.So this paper reviews the history of tunnel geological advanced prediction,including tunnel seismic prediction,horizontal sonic profiles,land sonic,ground penetrating radar,infrared detection,advanced boreholes and advanced tunnel in China,and then introduces its research progress in recent years.It analyzes their current situation and discusses their disadvantages of geometrical structure imaging,physical structure imaging and complex geological body detection.At last some existing problems such as basic theory study,forward and inversion study,multi-parameter utilization and building of 3D advanced alarm system have been pointed out.Some basic concepts to solve those problems have been provided.
