Pavement disease exploration method in urban shallow-buried tunnel construction

The invention relates to a pavement disease probing method in urban shallow-buried tunnel construction, which explores from three angles, and comprises the following steps of: acquiring a preliminary disease type and a disease position in a deep area from the ground to a first target layer depth, acquiring a preliminary disease type and a disease position in a set area in the tunneling direction of a tunnel main track tunnel face, and acquiring a preliminary disease type and a disease position in a set area in the tunneling direction of the tunnel main track tunnel face; the deep area, the shallow area and the set area all coincide with the exploration intersection area to a certain degree, it is ensured that data of the three parties can guide one another, comprehensive exploration is carried out in the shallow tunnel and in the two sets of depth ranges of the earth surface, and the detection accuracy is improved. According to the method, data of three parties are utilized, influences among diseases are comp
