Method for identifying rock mass structure on tunnel face based on fusion of ground penetrating radar and point cloud data

Abstract

A method for identifying a rock mass structure on a tunnel face based on fusion of ground penetrating radar and point cloud data, comprising the following steps: S1: acquiring data of a tunnel face to be identified; S2: generating an initial geological anomaly region set; S3: generating a candidate set for discontinuity planes; S4: projecting the initial geological anomaly region set into a three-dimensional space where the candidate set for rock mass discontinuity planes is located; S5: constructing a multi-source fusion feature vector; S6: outputting an identification result of the rock mass structure on the tunnel face. Compared with the prior art, the invention has the advantage of providing a method for identifying a rock mass structure on a tunnel face based on fusion of ground penetrating radar and point cloud data, which solves the problems in the prior art of incomplete information from a single detection means, difficulty in fusing multi-source data, and low identification accuracy, and achieves intelligent and precise identification of the tunnel rock mass structure.
