Bridge construction has received a lot of attention as transportation continues to improve. Reinforced concrete linked arch bridges are a common bridge style in today’s bridge construction. This type of bridge not only has a basic and generous shape, but it is also incredibly easy to construct, resulting in significant material and construction cost savings. This article analyzes the construction technology of a reinforced concrete linked arch bridge in order to achieve good construction and application. It is hoped that this analysis can provide a scientific reference for the guarantee of the construction quality and subsequent application effect of this kind of bridge.

The short line match-cast method of precast segments has proved to be the most versatile and reliable way to concrete bridge construction. The success of match-cast method relies heavily on accurate geometry control in precasting as the scale of adjustments during erection is very small and difficult to implement. So the required levels of accuracy in segments match-casting are stringent in order to assure erection accuracy. Therefore, the research on segments match-casting and geometry control technique of space distorted segments are very important.Based on the principle of match-casting using the short-line method, the geometry control technology of transition curve section in cross-sea bridge erected by precasting segment girder is proposed. As an example of south approach spans in north branch of Xia-zhang Cross-sea Bridge, this paper will provide a reference for the construction of similar bridges.

Large-span V structure tied arch bridge structure system is complex. In order to make the actual state of the bridge into the ideal state of maximum close to the design, we must make real-time monitoring in the key parts of the structure, and adjust to the design of the data by analysis calculated, to ensure the safety and reliability of arch bridge in the course of construction and into stress after the completed bridge. Combined with the construction monitoring of the main Xinglong Bridge on Si River, this paper introduces the main bridge construction process measurement a preliminary study on the large span V configuration basket tied arch bridge construction monitoring technology. Based on the construction monitoring of Xinglong Bridge on Si River, this paper introduces the main contents and methods of monitoring point location, monitoring control of construction process, and discussed the construction monitoring technology of long-span X-style tied arch bridge V structure.
