拱桥阻滑板的原理及应用

拱桥作为一种最常用的桥梁型式,存在着拱脚水平推力较大的缺点,阻滑板体系能够克服此缺点。该文推导了阻滑板的水平抗推刚度,并结合一工程实例分析了影响阻滑板抗推刚度的因素,最后,提出了施工中应注意的事项。

Principle and Application of Anti-slider in Arched Bridge

The arched bridge is the most used bridge type, but has such a drawback that the horizontal thrust at arch feet is big, which can be solved by the anti-slider system. This article derives the horizontal anti-thrust stiffness of anti-slider, and analyses the factors influencing the anti-thrust stiffness of anti-slider by an engineering example. Finally, the article puts forward the cautions for the construction.
