Abstract

Dispersive soil poses significant risks in civil engineering due to their susceptibility to erosion and structural instability, particularly in embankments, dams, and infrastructure. Since the discovery of dispersive soils, their dispersion mechanism has been a widely discussed and researched topic. This study introduces rough set theory to systematically analyze the dispersion mechanism of soils, aiming to identify the key factors influencing soil dispersion and their interrelationships. By analyzing eleven crucial parameters, including plastic limit, liquid limit, plasticity index, clay content, sodium ion (Na⁺), pH, and others, and validating the results through dispersion tests, the study finds that sodium ion and pH have the most significant influence on soil dispersion, with weights of 28.6% each. These are followed by plastic limit (19%) and liquid limit (14.3%), while clay content has a smaller effect (9.5%). These findings are critical for enhancing the stability and safety of infrastructure, especially in vulnerable regions.
