Shield slurry performance accurate detection method based on CT (Computed Tomography) technology

The invention relates to the technical field of slurry fluidity detection, in particular to a shield slurry performance accurate detection method based on a CT technology. Firstly, an internal structure image of slurry is divided into at least two local structure image blocks; according to the uniform area distribution and shape rule condition of the slurry particle region in each local structure image block, the slurry particle confusion degree is obtained; according to the time sequence change condition of the slurry particle confusion degree, the slurry particle distributivity representing the slurry flow blockage condition is obtained; and further according to the overall size, the stability and the angular point density of the slurry particle distribution in each local structure image block corresponding to the shield slurry, obtaining more accurate slurry fluidity corresponding to the shield slurry, so that more accurate shield slurry performance detection is carried out according to the slurry fluidity
