Abstract: The influence of support morphology on crushing strength was investigated using various methods. The results indicated that the crushing strength of the support has a certain distribution range, which conforms to a normal distribution. The crushing strength values, and corresponding morphological parameters were obtained using the Weibull analysis method. The impact of morphology on the extrusion of dry strips and the crushing strength of the support was also studied. It was found that the square-shaped columnar support had the highest strength, while the triangular support had the lowest. The proportion of the real part was not the key determinant of strength; instead, morphology had a significant impact on strength. Finite element analysis was employed to simulate the stress distribution during the compression process of supports with different morphologies, revealing that the low strength was due to structural collapse caused by local stress concentration.
