金水河特大桥悬灌梁施工技术研究

摘要

Combining with the construction of the super-large bridge over Jinshni River along Xi' an-Hanzhong Expressway, the paper explores the construction features of the cantilever-concreting beam, adopts the hanging basket dislocation parallel installation, the side span and middle span synchronous closure, and proves by the results that the cantilever-concreting beam construction at the super-large bridge along Jinshui Bridge provides a new and efficient construction technical scheme, it saved 0.5 million yuan for the investment, compared with the traditional craft, and the construction progress is brought forward about three months.%结合西（安）汉（中）高速公路金水河特大桥施工，探讨了悬灌梁施工特点，采用了挂篮错位平行安装、边跨与中跨同步合龙技术，结果表明，金水河特大桥悬灌梁施工提供了一种全新、高效的施工技术方案，较传统工艺节省投资50多万元，提前施工进度3个月。
