摘　　要：为节省土地资源,机场多建于山区,势必涉及土方深挖高填,由于山区地形地质条件复杂多变,加之填筑材料差异性、施工影响和人为因素的影响造成机场变形不均匀问题时有发生。结合工程实测数据,使用双曲线法、指数曲线法和Asaoka法对其进行工后沉降预测,同时通过对比,对影响双曲线法、指数曲线法和Asaoka法准确度的主要因素进行了分析,提出适合该机场的预测模型。In order to save land resources,airports are mostly built in mountainous areas,which will inevitably involve deep excavation and high fill of earthwork. Due to the complex and changeable terrain and geological conditions in mountainous areas,as well as the difference of filling materials,construction impact and human factors,the problem of uneven deformation of airports is inevitable. In this paper,combined with the actual engineering data,the hyperbolic method,exponential curve method and Asaoka method are used,at the same time,the main factors affecting the accuracy of hyperbolic method,exponential curve method and Asaoka method are analyzed.
