Combination of geological radar and video surveillance in the tunnel geological prediction

This paper presents the combination method between geological radar and video surveillance in the tunnel geological prediction, in case the randomness in judgment for the target body prone in the current geological advanced prediction. In order to improve the accuracy, this method conducts geological advanced prediction by comprehensive of geological radar, geological and construction information. In order to verify the effect of this method, we conducted a field trial in the Yululing tunnel. The field trial results are very well. And the accuracy of geological advanced prediction has been improved. This method reached the expected target for the accuracy which we want to improve of geological advanced prediction.
