| Abstract: | As an instrument of advanced geological forecast method in road tunnel,GPR(Ground Penetrating Radar)plays an important role to predict remote structure in the front of facing frontage and can be the further realization and supplement of tunnel prospect at the same time.On the basis of simply introducing the principle of electromagnetic wave of GPR in paper,it is successful to forecast the the faulted zone and ground water which exist in Xinzhagou tunnel using SIR-20 GPR and engineering geology technique.The... |
