摘要： 以西南地区某机场为工程背景，用离心模型试验研究高填方地基的沉降变形特征。试验结果表明，高填方地基填筑体的沉降变形特征为“沉降小，压实快”，沉降主要发生在施工期，工后期的沉降约为总沉降的10％左右。

Abstract: Based on the construction of an airport in high fill area in Southwest China, the settlement characteristics of the compacted fills is studied by the centrifugal model tests. The model test results indicate that the settlement of the high fill materials have a small settlement magnitude and fast rate. Approximately, 90% of the total settlement will occur during the construction and the post construction settlement consists of only 10% of the total settlement.

Key words: Centrifugal Model Test, High Embankment, Settlement
