大跨度预应力混凝土连续刚构桥挠度计算和施工控制
|
摘要
随着科学、技术及交通的快速发展,预应力混凝土连续刚构桥以其施工简便、造价经济、受力合理、行车舒适等独特优势在近年来得到了迅速崛起,在主跨100～300m范围内几乎成为首选桥型。而在预应力混凝土连续刚构桥悬臂施工过程中,建成梁段的线形在后期施工中是不可调节的,因此为了保证大桥的顺利合龙及成桥线形满足设计要求,同时成桥内力控制在设计容许范围内,必须对桥梁进行详细结构设计、施工设计和施工控制。
查阅大量文献资料,总结连续刚构桥及国内外施工控制的发展现状,以新龙大桥为例,介绍预应力混凝土连续刚构桥的设计,就结构尺寸方面和其它已建同类桥梁进行比较;对连续刚构桥进行施工设计;进行挠度精确计算并设置预拱度;阐述连续刚构桥悬臂施工过程中的高程控制原理,给出部分施工过程高程监控结果,并对实测值和理论计算值产生差异的原因进行较为详细的分析;对立模标高突变、预备束启用和合龙等连续刚构桥施工控制中三个重要问题进行较为深入的研究。
With the development of science, technology and traffic enterprise, the prestressed concrete continuous rigid frame bridge has been growing up rapidly in the recent years with it's special predominance of handy construction, economical cost, reasonable internal force and comfortable traveling. It almost has become the preferred bridge style when the main span is in the range from 100m to 300m. During the cantilever construction of the prestressed concrete continuous rigid frame bridge, the finished beam profile of formed segments can not be regulated in the late constructions. To ensure the smoothly closure of the bridge and satisfy the requirement of design profile in the completed stage of the bridge, it is necessary that the structurral design, construction design and construction control.
Consulting lots of professional literature, development actuality of continuous rigid frame bridge and construction control are summarized in the thesis. Taking XinLong Bridge as a typical example, the author introduces the design of the prestressed concrete continuous rigid frame bridge, and draws comparisons with other constructed bridges with same styles. Not only the construction process of the bridge is designed, but deflection and construction camber are only calculated accurately in the thesis. After listing the theory of leveling control during the construction of continuous rigid frame bridge, the author gives parts of the leveling control result, and analyzes particularly reasons cursed the difference between practice and theoretic. Finally, abrupt change of fabrication elevation, using of spare prestressing tendons and closure during the construction of long-span continuous rigid frame bridge construction are studied.
