| 摘 要： | 高速公路利用旋喷桩施工过程中的返出浆液，形成桩间系梁，不仅能减少环境污染，同时，提高了复合路基的承载力和抵抗变形的能力，以某高速公路旋喷桩复合路基为例，模拟分析了复合路基形成的全过程，对有无连系梁情况进行了对比分析，预测了高速公路路面的长期沉降变形，所获结果对工程具有参考价值。

| Abstract: | By means of concrete liquid returning to ground,beams between piles are formed in the process of composite foundation construction,which can reduce pollution of the environment and improve the bearing capability and resistance to deformation of composite foundation. In the paper,a whole process of formation of composite foundation is simulated by an example of a freeway. Composite roadbed with beams between piles is analyzed and compared with the case of no beams. The obtained results are of value for engineering reference. |
