钢管立柱支架法在南港特大桥悬浇梁现浇段中的应用

摘要

with the rapid development of expressway, railway construction, cross river, across the river and across other structures used in the span of the bridge is more and more big, cantilever Liang Yingyong is more and more widely.In view of the different span, cantilever beam side span lengths, not a pier, foundation bearing capacity is not one, led to the introduction of the support form difference.Through the introduction of Xi-azhang Expressway Extension Project of Zhangzhou section of 3 cantilever beam side span construction, how to save cost, ensure safety,Steel pipe column bracket.%　　随着高速公路、铁路建设的飞速发展，跨江、跨河及跨越其他结构物时采用的桥梁跨径越来越大，悬浇梁应用也越来越广泛。针对不同的跨径，悬浇梁边跨现浇段长短不一、墩高不一、地基承载力不一，导致采用的支架形式相差较大。通过介绍厦漳高速公路漳州段扩建工程3处悬浇梁边跨现浇段的施工，就如何节约成本、保证安全、确保质量方面进行研究。
