下承式变高度连续钢桁梁桥悬拼关键技术研究

Research on Key Cantilever Construction Technologies of Through Variable Height Continuous Steel Truss Beam Bridge

对下承式变高度连续钢桁梁桥悬拼施工技术研究,通过设计、计算分析,采用整体临时支墩、上下爬坡式起重机、墩顶调节装置等一系列有效的技术措施。保证了下承式变高度连续钢桁梁悬臂施工顺利进行。

This paper studies the cantilever construction technology of through variable height continuous steel truss beam bridge. Through the design and calculation and analysis, a series of effective technical measures are adopted, such as the integral temporary support pier, the climbing crane, the regulating device of top of the pier and so on. The cantilever construction of through variable height continuous steel truss beam is guaranteed.
