摘　　要：对安徽省膨胀土进行了综合试验研究。通过掺灰击实试验得出安徽主要膨胀土分布地区土样的最大干密度、最佳含水率与掺灰量的关系。对省内膨胀土的各种不良作用以及改良措施进行研究,为安徽省内工程建设提供必要的数据和合理化建议。This study carried out a comprehensive research on the expansive soil of Anhui Province. The relationship between maxi- mum dry density, optimum moisture ratio and lime-mixing content of soil samples from the main expansive soil distribution areas in An- hui was determined through lime-mixing tests. This work also analyzed the adverse effects and improvement measures of expansive soils in Anhui, which will provide necessary data and reasonable suggestions for the project construction in Anhui Province.
