| 摘 要： | 将控制变形桩原理应用于路桥协同沉降的设计思路中,开展如何控制桥梁桩基础沉降研究,应用减沉桩基础防止桥头跳车,打破传统的“路归路,桥归桥”的设计模式,进行路桥的设计优化,降低桥坡基础处理及桥梁桩基础工程造价,使桥梁与道路沉降协同.应用减沉桩基础为解决桥头跳车问题开辟了新途径,对具体工程的长期沉降观测表明,该方法是完全可行的.

| Abstract: | Based on application of reducing-settlement pile foundation to preventing vehicle pitch at bridge approach,design frame and method of reducing settlement between bridge and roadbed is introduced.This method not only break out traditional "road is road,bridge is bridge" design mode,but also create a new approach for preventing vehicle pitch.Through long-term settlement observation on the engineering example,it is proved that this method is effective and successful. |
