高填方填筑体沉降变形影响因素研究

Influence Factors of Settlement Deformation of High Filling

在分析西南地区已有的高填方机场地形影响沉降变形的基础上,以重庆机场为例建立理论模型并进行数值分析,得到地形影响沉降变形的基本特征,然后按照一定的比例在离心机模型箱中建立实际模型并进行离心试验,通过对实验数据进行分析与研究,总结地形影响高填方填筑体沉降变形的特点,并为后续的高填方工程提供一定的指导.

Based on the topographic influence of the high filling airports as well as their settlement deformation in southwest of China,and by taking the Chongqing airport as an example to establish theoretical model and then doing numerical analysis of it,the basic characteristics of topographic influence on settlement deformation are obtained.Then according to certain proportion,an actual model is set up in the centrifuge model box and a centrifugal experiment is done.Through the analysis and study of the experimental data,the characteristics of topographic influence on high filling embankment settlement deformation are summarized and some guidance for subsequent high filling projects is provided.
