| 摘 要： | 以四川省九寨黄龙机场高填方地基工后沉降原位监测结果为基础,探讨了高填方地基工后沉降预测回归参数模型。在指数模型、幂函数模型、平方根模型、双曲线模型和对数模型等回归参数模型中,只有对数模型能较真实反映高填方地基工后沉降规律。对数模型的预测结果表明,由于高填方地基中上部填筑体和底部软弱地基填筑厚度极不均匀,工后差异沉降显著。

| Abstract: | Based on the in-situ monitoring data of the post- construction settlement of the high embankment of Jiuzhai-Huanglong airport, some regressive parameters models are discussed to predict the post-construction settlement. All exponential models, power function models, root-squaring models, hyperbolic models, but logarithm models can’t disclose the laws of the post- construction settlement of the high embankment. The predicted results with logarithm models show that due to the varation of the thickness of the underlying weak stratom and the upper filled soil, the differential settlement of the high embankment is remarkable. |
