Embodiment Construction
[0011] Refer to Figure 1, an electro-seismic comprehensive imaging diagnosis method for the compaction quality of a soil-rock mixed roadbed. The method includes the following steps: 1) Perform a vibration imaging test on the soil-rock mixed roadbed; 2) Perform apparent resistance on the soil-rock mixed roadbed Rate imaging test; 3) Analyze and process the test signals obtained in step 1) and step 2); 4) Perform imaging inversion on the distribution of road-base wave speed and apparent resistivity to obtain road-base wave speed images and apparent resistivity images; 5 ) Calculate the distribution of subgrade compaction degree to obtain compaction degree image; 6) Diagnose the subgrade compaction quality according to the degree of compaction image.
[0012] On-site vibration imaging test
[0013] Refer to Figure 2 for the on-site vibration imaging test method. The test steps are:
[0014] 1) Place 6-12 vibration pick-ups or geophones on the surface of the soil-rock mixed roadbed. T...
