Spatiotemporal laws of post-construction settlement of loess-filled foundation of Lüliang Airport

Based on the monitoring results of the post-construction settlement of the loess-filled embankment foundation of Lüliang Airport, the components of the post-construction settlement of the high fill and the original foundation and the causes of uneven settlement are analyzed. The influence factors such as the height of fill, filling rate, general compaction degree and time on the post-construction settlement are quantitatively analyzed. The recursive analysis method based on the strain rate is proposed to predict the post-construction settlement. The results show that the decrease of the filling rate, appropriate increase of foundation compaction degree and decrease of filling height are the effective measures to reduce the post-construction settlement. The recursive analysis can more approximately describe the effect of construction technology on post-construction settlement.
