| 摘 要： | 随着高速公路的兴起，复合地基应用越来越普遍，且复合地基的沉降变形日益受到关注。采用FLAC3D软件，建立单桩复合地基模型，在分别分析沉降单一影响因素的基础上，进一步引入正交设计软件，分析多因素多水平组合下复合地基的沉降变形，并进行前后的对比分析，得出单一影响因素最佳水平取值的机械组合，并不能取得理想的降低复合地基沉降效果的结论。

Analysis on Factors Affecting Settlement of Single-pile Composite Foundation Based on Orthogonal Experiment |
| |
| Abstract: | As development of highway，composite foundation is more and more popular so that its settlement deformation becomes a concern.With FLAC3D software，the model of single-pile composite foundation was established.Based on the respective analysis of each factor affecting the settlement thereof，with orthogonal design software introduced，the deformation resulting from the combination of various factors at multiple levels was studied，and then the comparison with the former studies was conducted.As a result，it was concluded that the mechanical combination of each factor at its optimal value level can not obtain ideal effect on reducing settlement of the composite foundation. |
