摘　　要：在高填方工程中,施工过程中和施工完成后不同部位填筑体的沉降特性非常重要,会直接影响到后续工程的开工日期。为了分析填筑体内部的沉降特性,介绍了分层沉降监测装置的安装埋设及观测方法,结合昆明机场高填方区分层沉降监测数据进行了沉降原因分析,最后采用双曲线模型及对数曲线模型对沉降监测成果进行了沉降预测分析。结果表明:引起填筑体分层沉降的主要因素为填料类型及填筑工艺;双曲线模型及对数曲线模型用在高填方分层沉降预测中是可行的,且预测精度良好。In high embankment projects, the settlement of filling body during or after the construction means a lot and will decide when the follow - up will be constructed. This paper first analyzes the settle-ment of filling body and introduces the installing and surveying method of layered settlement monitoring e-quipment. Based on the data analysis at Kunming Airport, it then makes the settlement prediction with hyperbolic model and logarithmic curve models. The results show that the layered settlement lies in the filling type and filling technology, and that the two models mentioned above are feasible to not only pre-dict but predict accurately the layered settlement in high embankment areas.
