摘要

This study investigates the effectiveness of lime combined with sugarcane bagasse fiber (SBF) in improving the compression behavior of high-water-content dredged material. One-dimensional compression tests were conducted on lime-SBF-stabilized dredged soil samples with different SBF contents cured for 3 hours, 7 days, and 28 days. The results demonstrate that lime-SBF treatment significantly reduces sediment compressibility compared with untreated material. The compression coefficient decreased by 27-92%, while stiffness and yield stress increased markedly with increasing SBF content and curing time. Unlike untreated sediment, stabilized specimens exhibited a distinct two-stage compression behavior characterized by a clear compression yield stress. In the pre-yield stage, the treated sediment showed high stiffness and minimal compressibility, whereas a sharp increase in compressibility occurred after yield due to partial breakdown of cemented structures. An optimal SBF content of approximately 1.5% was identified, providing the greatest reduction in post-yield compressibility and the highest yield stress. SEM observations revealed that lime-induced cementitious products filled pore spaces and bonded soil particles, while SBF formed a reinforcing network that enhanced particle interlocking and restricted deformation. The combined use of lime and sugarcane bagasse fiber effectively improves the compression behavior and structural integrity of high-water-content dredged sediment.
