    Research on the disintegration characteristics of fissured loess under water–vibration coupling effect by Tao Lei, Jiading Wang, Shaotong Jiao

    Published 2025-05-01
    “…The influence patterns of vibration frequency (f) and fissure type (t) on disintegration rate (S), disintegration velocity (V), and disintegration velocity growth rate ( $$\alpha_{f - t}$$ ) were systematically investigated, with scanning electron microscopy (SEM) employed to uncover microstructural evolution mechanisms. Results indicate that vibration frequency and fissure type significantly accelerate disintegration: V reaches its maximum at f = 20 Hz, and under the same frequency, V increases with the growth of fissure-water contact area. …”
