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。
With the rapid development of highways and railways, bridges spanning the river, crossing the river and other structures are becoming more and more widely spanned, and cantilevered beams are also used more and more widely. For different span, the cast-in-situ cast-in-situ beams have different length of cast-in-situ sections, different piers and different foundation bearing capacity, resulting in large differences in the forms of supports. Through introducing the construction of 3 cast-in-situ cast-in-situ cantilevered beams of Zhangzhou section expansion project of Xiamen-Zhangzhou expressway, the research on how to save costs, ensure safety and ensure the quality is carried out.
