Abstract

Due to the special engineering environment and construction technology of Liuyingmen StationWufutang Station shield section of Phase 3 of Beijing Metro Line No. 8, the conventional geological prediction method is hard to be carried out. The characteristics of phase position and vibration amplitude of seismic wave are analyzed by regarding the cutting vibration of shield cutterhead as vibration source and seismic reflection method as principle; the advanced geological prediction method based on seismic reflection method for shield tunneling is proposed; and then the advanced geological prediction and relevant tracking work are carried out. The field test shows that: 1) The abovementioned geological prediction method is easy in layout and convenient in operation and does not affect shield advancing. 2) The shapes and contours of underground bodies can be well reflected by the abovementioned geological prediction method, and the interpretation of the prediction results coincides with the actual data.
