摘　　要：为了解决机场膨胀土的评判标准单一及处理工法适宜性问题,本文在研究膨胀土对机场场道工程危害的基础上,结合其他行业的判定标准,就膨胀潜势的划分提出适合机场场道工程的多因素评判标准;其次,在总结已建机场膨胀土处理工法和处理深度的基础上,根据场地不同分区和膨胀潜势等级给出适合机场场道工程的膨胀土推荐处理工法、推荐处理深度及处理范围。In order to solve the problems of single evaluation standard of airport expansive soil and the suitability of the treatment method, based on the study of the harm of expansive soil to airport road project, combined with the judgment standards of other industries, this paper puts forward the multi-factor evaluation standard suitable for airport road project on the division of expansion potential. Secondly, on the basis of summarizing the treatment method and treatment depth of expansive soil in built airports, the recommended treatment method,treatment depth and treatment range of expansive soil suitable for airport runway project are given according to different zoning and expansion potential level of the site.
