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
