This study repurposed discarded carbon fiber fabric by mechanically cutting it into short-cut carbon fibers and utilized these fibers in electro-osmosis experiments with varying lengths (5 mm, 10 mm, and 15 mm) and mixing ratios (0.05%, 0.10%, and 0.25%). The results indicated that increasing the length and mixing ratio of recycled carbon fibers effectively reduced the soil resistivity. Furthermore, incorporating an appropriate amount of carbon fibers not only reduced the energy consumption coefficient but also enhanced the electro-osmotic drainage performance. Increasing the length and mixing ratio of carbon fiber also improved the vane shear strength after electro-osmosis consolidation. To promote the application of carbon fiber in electro-osmosis consolidation and to provide support for the development of electro-osmosis consolidation theory and numerical analysis, a resistivity calculation model of carbon fiber-reinforced soil during the electro-osmosis process was developed based on the Ohm's Law and tunneling transmission theory. The model elucidates that during the electro-osmosis process, soil resistivity is influenced by the increase in barrier thickness, which consequently raises the tunneling transmission resistance.

再生碳纤维增强软粘土的电渗固结和电阻率演化特征


本研究通过将废弃的碳纤维织物机械切割成短切碳纤维来重新利用，并在不同长度（5 毫米、10 毫米和 15 毫米）和混合比例（0.05%、0.10% 和 0.25%）的电渗透实验中使用这些纤维。结果表明，增加再生碳纤维的长度和混合比可有效降低土壤电阻率。此外，掺入适量的碳纤维不仅降低了能耗系数，还提高了电渗排水性能。增加碳纤维的长度和混合比也提高了电渗透固结后的叶片剪切强度。为促进碳纤维在电渗透固结中的应用，为电渗固结理论和数值分析的发展提供支撑，基于欧姆定律和隧穿传输理论，建立了碳纤维增强土在电渗过程中的电阻率计算模型。该模型阐明，在电渗过程中，土壤电阻率受屏障厚度增加的影响，从而提高了隧道传输阻力。
