Construction Technology Of Large-Span Prestressed Concrete V-Piers Continuous Rigid Frame Bridge

V-pier continuous rigid frame bridge structure, when compared with traditional beam, has its unique advantages, which can be shown in several areas: more reasonable structure, force structure greatly increased stiffness, V-piers beautiful shape, structure, nice configuration. It is a kind of very light and beautiful bridge. Therefore, it is often adopted in the modern long-span bridges, especially in the case of high requirement to landscape.In this thesis, taking Guangzhou-Zhuhai intercity rapid rail project Xiao Lan waterway bridge as engineering background, the whole text is divided into five chapters. The first chapter is introduction, which focuses on long-span continuous rigid frame bridge, descrbing the characteristics and major construction technology and construction monitoring. Chapter Two covers the, the overview and construction of the bridge Xiao Lan waterways, including engineering profiles, technical standards and other aspects. Chapter Three gives the main bridge construction technology, packet inter-V-piers, tie beam and continuous rigid frame. Chapter Four is on structural calculations under the construction stage. Chapter Five is for construction monitoring, which plays a crucial role in the construction process, mainly through monitoring and stress and configuration.
