摘　　要：毕节机场位于贵州毕节的东南方,属喀斯特区中心地带,碳酸性岩盐红粘土广泛分布。毕节机场红粘土地基的物理力学性质较差,对机场填方边坡稳定性和机场跑道的沉降与不均匀沉降影响大。本文根据现场勘察及地基处理检测资料,对毕节机场红粘土的空间分布特征、基本物理力学性质、红粘土地基的承载特性、击实特性和膨胀性进行阐述,在此基础上提出了红粘土地基的加固处理方案。Bijie Airport, located in Bijie＇ s southeast of Guizhou, belongs to the center of karst district ,and the red clay of carbonate rock salt is distributed there widely. The physical and mechanical properties of Bijie Airport＇ s red clay foundation are very bad, having great influence on the airport filling slope＇s stability and the airport runway＇ s uneven settlement and settlement. Here, according to the investigation and test results of foundation treating, such aspects are expounded as the space distribution features, the basic physics and mechanics, the foundation＇s carrying characteristics, the compaction characteristics and the expansibility of the red clay of Bijie Airport. Based on this, the red clay foundation＇ s reinforcement scheme is proposed.
