摘要：

通过对河北省承德高填方机场工后沉降进行监测，对填筑体高度与工后沉降之间的变化规律进行分析，对工程中常用的沉降预测方法进行比较，探讨了高填方蠕变实用算法在工后沉降预测中的应用，并以该方法为基础，提出了沉降稳定速率和稳定时间的预测方法。结果表明：高填方工程中填筑体高度与工后沉降呈线性增长关系，是影响工后沉降量大小的重要因素，高填方蠕变实用算法可较好地预测工后沉降，该方法可预测工后沉降稳定速率和稳定时间，为何时进行道面铺设提供参考。

Abstract:

Through monitoring of post-construction settlement of Chengde Airport in Hebei Province, the variation law between height of filled body and post-construction settlement is analyzed. By comparing the settlement prediction methods commonly used in engineering. the application of high filling practical creep computation algorithm in post-construction settlement prediction is discussed. Based on this method, a prediction method of foundation stability rate and foundation stability time is proposed. Result shows that the variation law between height of filling body and post-construction settlement is linear and there exists a significant factor affecting the post-construction settlement in high filling project. The high filled creep practical algorithm can predict the developing trend of
post-construction settlement, the prediction of foundation stability rate and foundation stability time can provide a reference for subsequent pavement planning.

Key words: high filling engineering, post-construction settlement monitoring, post-construction settlement prediction
