Description
Technical field
Interpretation technique field is detected the present invention relates to underground disease more particularly to a kind of using Ground Penetrating Radar spy
Underground disease is surveyed, joint interpretation can be carried out to more sections, convenient for comparing the similarities and differences of adjacent sections underground disease, row
Except external interference is abnormal (such as underground utilities), the areal extent and spatial of underground disease exception, means of interpretation speed are estimated
Fastly, high-efficient, time saving and energy saving, accurately and reliably use the more section joint interpretation methods of ground penetrating radar detection underground disease.
Background technique
When Ground Penetrating Radar, which is applied to underground deep layer recessiveness disease, to be detected, road is generally divided into two width, driving
It is contrary, and every width is made of the consistent multiple lanes of direction of traffic.For all standing, exhaustively to disease below road
It is detected, needs each lane to arrange a Ground Penetrating Radar survey line, to obtain a plurality of Gpr Data.Typically,
Otherness between adjacent lane underground medium is smaller, consistency and relevance with higher between Gpr Data.It is logical
The underground disease exception for comparing adjacent Gpr Data is crossed, it is abnormal (such as underground utilities) convenient for excluding external interference, estimation
Lower disease spatial and areal extent.Traditional Coherent Noise in GPR Record means of interpretation is solved one by one to Gpr Data
It releases, i.e., is classified underground disease in section (as the soil is porous, empty and rich extremely according to mileage pile No. or apart from sequence
Water etc.) and classification (such as slight, medium and serious) interpretation, then classify or is classified disease anomaly statistics table under output ground or cuts open
Face figure, the sequence of the underground disease exception of section each in this way be it is independent, have no to be associated with each other between section, thus section it
Between underground disease also have no way of comparing extremely.When underground (serious) disease to a certain multiple lanes of road is verified,
It needs according to the artificial sequence of distance sequence, time-consuming and laborious and error-prone, working efficiency is lower.
Summary of the invention
The present invention is the underground disease solved between section possessed by existing underground disease detection means of interpretation
Exception has no way of comparing, artificial to sort, time-consuming and laborious and error-prone problem, and provides a kind of using ground penetrating radar detection road
Underground disease, joint interpretation can be carried out to more sections, convenient for comparing the similarities and differences of adjacent sections underground disease, excluded extraneous
Interfere abnormal (such as underground utilities), estimate the areal extent and spatial of underground disease exception, means of interpretation speed fastly, efficiency
It is high, time saving and energy saving, accurately and reliably use the more section joint interpretation methods of ground penetrating radar detection underground disease.
The technical solution adopted by the present invention is that:
Using the more section joint interpretation methods of ground penetrating radar detection underground disease, include the following steps:
Step 1) lays a Ground Penetrating Radar for all lanes in the road of required detection, explanation underground disease respectively
Survey line；
Step 2, the Ground Penetrating Radar survey line in each lane obtain multiple Gpr Datas to each ground penetrating radar detection,
Each Gpr Data includes the underground defect information of the lane Ground Penetrating Radar survey line position；
Step 3), the interpretation that Damage Types, severity level are carried out to the underground defect information in each Gpr Data,
Classification interpretation is carried out to disease；
Step 4), in a Gpr Data, select different type, the underground disease of different severity level to carry out defeated
Out, the output of each underground disease is saved as into a monomer disease file；
The monomer disease file that multiple Gpr Datas export all is saved in monomer disease library by step 5)；
Step 6), all monomer disease files in monomer disease library are fully open, data all call in memory, according to
Each distance of the disease position away from Ground Penetrating Radar survey line starting point, by the unified sequence of all monomer diseases, number consecutively；Away from spy land mine
It sorts up to survey line starting point apart from nearest underground disease near preceding, number 1, and so on, apart from Ground Penetrating Radar survey line starting point
Distance is closer, sorts more forward, and number is smaller, remoter apart from starting point, and sequence more rearward, is numbered bigger.
Further, Ground Penetrating Radar survey line described in step 1) is located at lane center position.
Further, underground Damage Types described in step 3) includes that the soil is porous, empty and rich water；The underground disease
Grade includes slight, medium and serious.
Further, it is Damage Types, disease grade, disease radar that the file of monomer disease described in step 4), which includes information,
Map, disease location information, place lane information.
Further, the disease location information is disease GPS information and disease midpoint away from Ground Penetrating Radar survey line starting point
Range information.
Further, to be each lane select measurement starting point by its direction of traffic to the Ground Penetrating Radar survey line starting point respectively is
Ground Penetrating Radar survey line starting point.
Further, the Ground Penetrating Radar survey line starting point is that each lane is unified according to the selected measurement starting of single direction of traffic
Point is Ground Penetrating Radar survey line starting point.
The beneficial effects of the present invention are:
(1) it is all to be applied to a certain multiple lanes of output for the more section joint interpretation methods of ground penetrating radar detection underground disease
When the scene encryption repetition measurement verifying of repetition measurement point is single, can all repetition measurements in the multiple lanes of this be pressed with the distance of range survey line starting point
Carry out unification, auto-sequencing, i.e., it is closer apart from starting point distance, it sorts more forward, number is smaller, and remoter apart from starting point, sequence is got over
Rearward, it numbers bigger.This method is time saving and energy saving, efficiently correct, and the sequence of repetition measurement point is consistent with direction of traffic, from small to large,
It successively verifies, can guarantee to carry out encryption repetition measurement verifying in scene along direction of traffic, guarantee that field condition encryption is multiple to avoid driving in the wrong direction
Orderly, the safety of test card work.
(2) the more section joint interpretation methods of ground penetrating radar detection underground disease are applied to output all vehicles of two width of road
It, can be to all underground diseases in all lanes of two width of road according to away from a certain width survey line starting point when all underground diseases in road are reported
Distance carries out unification, auto-sequencing, i.e., closer apart from starting point distance, sorts more forward, numbers smaller, row remoter apart from starting point
Sequence more rearward, is numbered bigger.In this way, it is abnormal (as to exclude external interference by convenient for comparing the similarities and differences for being adjacent to lower disease
Underground pipelines), it estimates the areal extent and spatial of underground disease exception, explanation speed can be effectively improved, improve and explain accurately
Rate.
In short, provided by the invention have energy using the more section joint interpretation methods of ground penetrating radar detection underground disease
Enough to carry out joint interpretation to more sections, means of interpretation speed is fast, high-efficient, time saving and energy saving, accurate and reliable advantage.
