| 摘 要： | 结合高速公路试验段的现场监测结果分析，探讨粉喷桩复合地基的沉降规律及沉降预测方法。试验研究的结果表明：粉喷桩复合地基具有工后沉降小、沉降量收敛速度快等优点；在预压期粉喷桩复合路基沉降与桩身压缩性成比例；分层总和法用于预测粉喷桩路基沉降量，效果不理想；双曲线法和灰色GM（1，1）模型比较适合用于粉喷桩复合路基沉降预测。而三点法则不适宜。

| Abstract: | The settlement characteristic and prediction method of DJM piles composite foundation are studied.It shows that:(1) the DJM piles foundation has advantages like as small post-construction settlement and fast stability,(2) during the preloading,the settlement is proportionate to the compression of the DJM piles,(3) laminar summation method is unsuitable to predict the settlement of DJM piles and(4) the Hyperbola Method and GM(1,1) Mode are fit for predicting the DJM composite foundation settlement,but the There Point Method isn't. |

| Keywords: | traffic engineering soft foundation improving settlement DJM piles |
