摘　　要：膨胀土问题是引江济汉工程的主要工程地质问题之一。在对工程区膨胀土进行大量的勘察、试验研究的基础上,论述了膨胀土的工程特性及沿渠线的分布特征。经对比分析,找出了适合本工程区特点的分类指标及分类方法,并对强度参数的取值作了深入的研究。在对膨胀土渠坡进行稳定性计算分析之后,提出工程处理措施的建议。The expansive soil is one of the main engineering geological problems of water diversion works from Yangtze River to Hanjiang River. Based on a large amount of investigation and tests on expansive soil in the project area, we describe the engineering characteristics of expansive soil and its distribution along the canal line. Through comparative analysis, we find out the classification indexes and methods which are suitable for the characteristics of project area and carry out further study on the selection of strength parameters. After the stability calculation and analysis of the expansive soil canal slope, the engineering treatment measures are proposed.
