贝雷桁架挂篮的设计与应用

Design and Application of Bailey Truss Form Traveler

悬臂浇筑法是一种大跨预应力连续梁桥常见的施工方法,广泛采用挂篮进行悬臂浇筑施工。由于贝雷桁架挂篮具有适应能力强、使用安全方便、造价较低等特点,故贝雷桁架挂篮得到了广泛应用。该文结合上海镇坪路跨苏州河桥的悬臂施工,对贝雷桁架挂篮的设计与应用进行了研究,并介绍了其应用的情况,以期能为同类工程施工提供一定参考。

The cantilever pouring method is a construction method commonly used for a long-span pre-stressed continuous beam bridge.The form traveler is widely used for the cantilever pouring construction.The Bailey truss form traveler is widely used because of its characteristics of strong adaptive faculty,convenient use safety,lower construction cost and etc.According to the cantilever construction of Shanghai Zhenping Road Bridge crossing Suzhou River,the article studies the design and application of Bailey truss form traveler,and introduces its application,which can be referred for the construction of the similar projects.
