Research on the Prediction of High Embankment Settlement Based on the Real-Time Monitoring On-Site

Abstract

Based on the real-time settlement monitoring of embankment on-site, Hyperbola method and Index curve method are used in the prediction of embankment settlement and the prediction results were compared to verify the feasibility and the potential engineering value of the prediction of embankment settlement. The calculation results showed that the relative error of the results calculated by the above methods was controlled within 2%. The accuracy of early settlement prediction of Index curve method was lower than the accuracy of later settlement prediction, but the predicting result met the needs of the engineering accuracy. The accuracy of settlement prediction of Hyperbola method was significantly higher than Index curve method. Through the comparing and analyzing of the prediction results of embankment settlement, the final settlement value calculated by Hyperbola method was higher than the real-time monitoring on-site, and the final settlement value calculated by Index curve method was lower than the real-time monitoring on-site, Hyperbola method is more suitable for the estimation to the subsidence of actual embankment engineering construction.
