Study on Karst Detection Methods of Railway Subgrade Based on Integrated Geophysical Prospecting Technology
The traditional karst detection method in railway subgrade directly draws the geological section without statistics of rocks'physical parameters,resulting in low detection efficiency.Based on the integrated geophysical prospecting technology,the karst detection method in railway subgrade is put forward.By collecting many groups of rock samples,their physical property parameters were recorded and then submitted to the computer software for geological section drawing.With the integrated geophysical prospecting technology,different rocks and soils were explored,and the exploration results were then added to the geological section to realize the karst detection of railway subgrade based on the integrated geophysical prospecting technology.A comparative experiment was also designed,and the experimental results showed that the method has higher detection efficiency.
