| 摘 要： | 针对中国高等级公路路桥过渡段出现桥头跳车病害，通过室内模型试验，结合土工格室楔形柔性搭板处治方法，研究了在不同工况下楔型柔性搭板的工作性状。结果表明，楔型柔性搭板能够有效地减小因地基沉降所引发的桥台台后填土沉降；对于不同土质，楔型柔性搭板减小沉降的效果有差异。提出了针对不同土质及不同沉降条件下楔型柔性搭板的设计优化方案。

| Abstract: | In order to avoid the jump at abutment joint on high-grade highway, the treating method of wedge-shaped flexible approach slab that is consisted of geocell was discussed. The active mechanism of wedge-shaped flexible approach slab at different case was studied through the model experiment.The result shows that wedge-shaped flexible approach slab can effectively decrease the settlement of filling at back abutment caused by the foundation settlement; the effect has difference for various nature of soil.As a result, the designing optimization scheme for wedge-shaped flexible approach slab against different nature of soil and settlement condition was put forward.5 tabs, 10 figs, 6 refs. |
