Analysis of the distribution patterns and engineering characteristics correlation of expansive soil along the Yangtze-to-Huaihe River water diversion project
Through statistical analysis of a large amount of expansive soil data from the Yangtze-to-Huaihe River water diver-sion project,including the Yangtze River to Chaohu Lake section and the Yangtze River connecting the Huaihe River section,this study revealed the spatial distribution pattern of expansive soil along the route and the correlation between expansiveness and various physical and mechanical properties.The research results indicated that expansive soil along the Yangtze-to-Huai-he River water diversion project were primarily distributed in geomorphic units such as low mountains,hills,and mounds,with expansiveness mainly ranging from weak to moderate expansion potential.The strength of expansiveness was significantly influ-enced by plasticity limits,liquid limit,clay content,and plasticity index,while it was less affected by water content and cohe-sion,which were related to strength properties.The study constructed a multiple regression prediction model for free swell ratio based on the main controlling factors,aiming to provide a reference for the future analysis of expansive soil.
