摘要
结合杨家岭特大桥施工实例,介绍了在高墩连续刚构桥梁0号梁段施工时应用预应力技术,对高墩托架进行预压的方法,并与传统堆载的预压法进行了比较。
With the construction practice of Yangjialing Extra-large Bridge, this paper introduces the method of applying prestressing technology to preload high-pier brackets in the construction of 0^# girder section of the continuous rigid-frame bridge with high-piers. Also, a comparison is made between this method and the traditional preloading method.
