To ensure the tunnel completion in tmi e and speed up the construction process, th is paper researches the usage methods, work ing contents, work ing procedures and data analysis methods of the advanced prediction and forecast technology TSP 203 for rap id and accurate surveying the engineering geological and hydrogeological conditions ahead of the tunnel. Research conclusions: TSP 203 can accurately predict the nature, location and scale of the rock body in the area of 100- 1 0 m ahead of the tunne,l especially the unfavorable geology, such as karst caves, fau lt zone and fracture zone. Application of TSP 203 in tunnel construction can reduce the blindness in tunnel construction, effectively prevent the appearances of the unfavorable geological d isaster and construction accidents, and speed up the construction progress. ey words: tunnel construction; TSP 203; prediction; forecast , , , , , , , , , , , , , , , : 2009- 12- 1
