探析大跨径预应力混凝土桥梁设计技术

On the Design Technology of Long-Span Prestressed Concrete Bridge

工程建设的规模在社会发展速度不断加快的背景下也在逐渐扩张,但因施工技术的影响及多种外部因素的制约,实际的施工质量也会受到很多因素的影响。归根结底,制约大跨径桥梁施工质量的主要因素还是施工技术,对于当下的大跨径桥梁建设来说,常用的施工技术手段就是预应力混凝土技术,虽然这种技术在较大程度上实现了施工质量的提高,但因施工技术相较于其他技术来说复杂性较高,若是施工操作人员施工阶段未能按照既定的施工规范要求完成工作,导致的质量问题就会较为明显。基于此,本文在现有施工的基础上,对于桥梁施工过程中的大跨径预应力混凝土桥梁设计技术的应用状态进行分析,以求加快桥梁施工质量优化,为后期的桥梁施工水平提升奠定基础。

Under the background of accelerating social development,the scale of engineering construction is also gradually expanding.However,due to the influence of construction technology and constraints of various external factors,the actual construction quality will also be affected by many aspects.In the final analysis,the main factor re‐stricting the construction quality of long-span bridges is construction technology.For the current long-span bridge construction,the commonly used construction technology is prestressed concrete technology,although this tech‐nology realizes the optimization of construction quality to a great extent.However,because the construction tech‐nology is more complex than other technologies,if the construction operators fail to complete the work according to the established construction specifications in the construction stage,the quality problems will be more obvious.Therefore,based on the existing construction,this paper analyzes the application status of long-span prestressed concrete bridge design technology in the process of bridge construction,in order to speed up the optimization of bridge construction quality and lay a foundation for the improvement of bridge construction level in the later stage.
