The term “engineering cancer” refers to expansive soil, whose properties threaten the stability and safety of structures. As a result, appropriate steps must be taken guarantee sustainable development buildings. To explore impact freeze–thaw cycles (FTCs) on microscopic characteristics unsaturated soil in cold region, mineralogical composition microstructure were analyzed using X-ray diffraction (XRD), thermogravimetric analysis, scanning electron microscopy (SEM). influence repeated FTCs particle morphology pore structure was quantitatively examined. findings indicate that, comparison other samples, Yanji is particularly susceptible failures due its high sand content low liquid limit. significantly alter microstructure, leading increased complexity edge shapes, transition distribution from dispersed more concentrated, reduction larger particles, intricate spatial arrangement particles. moisture rises, becomes increasingly pronounced. distribution’s area probability index fractal dimension are identified as medium-variability parameters, with high-variation coefficient before 3rd FTC, which then gradually decreases. result breakage agglomeration, causing size become uniform soil’s stabilize after 3–5 FTCs. These contribute understanding FTC behavior soils, provide theoretical support scientific guidance for disaster prevention control measures, well engineering projects involving sites.

To examine the effect of flocculation treatment on slurry clogging during vacuum preloading, this study conducted preloading model tests using lime, anionic polyacrylamide (APAM), and dual use polyaluminum chloride (PAC) APAM in conjunction with particle image velocimetry (PIV) analysis. The results demonstrated that enhanced efficiency mitigated slurry. Compared to untreated slurry, lime-flocculated exhibited an approximately 248% increase pore water pressure dissipation, a 462% zone width, 80% improvement strength near PVD. PAC significantly improved slurry’s filtration performance by 77 s, resulting highest discharge rate (47% higher than slurry) under pressure. In contrast, alone primarily early stages but had limited final volume horizontal strain. Furthermore, investigated evolution flocculated elucidated underlying mechanism mitigating findings can provide theoretical basis for selection flocculants arrangement PVDs large-scale land reclamation dredged projects.
