摘　　要：为了探明某机场航站楼地坪鼓胀的原因及其发生机理,通过对场地内采取的素土和灰土土样进行试验、分析,在掌握大量试验数据的基础上,揭示了灰土地基鼓胀的原因是地基土中存在一定量的硫酸盐,并在外界一定条件的诱发下生成了钙矾石和碳硫硅钙石,造成灰土地基鼓胀的机理,得出了应加强对灰土配合原料中硫酸盐含量的检测的结论,对类似工程具有一定的借鉴意义。In order to find out the reason and mechanism of the expansion of the airport terminal Iloor, through the experiment and analysis of the soil and the soil samples taken in the site, and on the basis of mastering a large amount of test data, found that the reason of the expansion of the land base was that there was a certain amount of sulfate in the base soil, and the ettringite and the carbon and sulfurite were formed under the condition of certain conditions, which caused the mechanism of the bulging of the gray soil. It was concluded that the determination of sulfate content in the combination of lime and soil should be strengthened, which had a certain reference significance for similar projects.
