The invention provides an in-situ correction roadway loose zone testing method based on a DeeplabV3 + language segmentation
algorithm, and relates to the field of roadway loose zone testing, and the method comprises the following steps: drilling a hole underground, obtaining a
rock core, obtaining a test
drill hole, and obtaining a
wave velocity-double
collection time-test depth curve graph of the loose zone test
drill hole by using a single-hole
ultrasonic velocity measurement method; analyzing according to the
wave velocity-double receiving time-test depth curve graph to obtain the
longitudinal wave velocity of the original rock
mass; utilizing the obtained
rock core to obtain the position of a rock
mass deep loose circle by combining a co-location discrimination method with a
wave velocity-double receiving time-test depth curve graph; a drilling optical
electron microscope method based on a DeeplabV3 + language segmentation
algorithm is utilized to identify cracks and
lithology data on the surface of a hole wall, and the
lithology data are combined to analyze surface cracks actually influencing the surrounding rock loose circle; and the real range of the roadway surrounding rock loosening circle is given by combining the position of the rock
mass deep loosening circle and the cracks and
lithology of the hole wall surface. The method disclosed by the invention has certain guiding significance on supporting and optimized supporting of the roadway.
