Continuous Rigid Frame Bridge Construction Safety Technology Research

In recent years, with the rapid development of our country highway transportationenterprise, Spanning capacity of bridges is more and more strong, all kinds of long-spanbridge are constructing in our country, which frequently adopted in the design of prestressedconcrete continuous rigid frame bridge in particular. With the same kind bridge (such ascontinuous girder bridge, T rigid frame bridge): multi span bridge keeps the upper structureof continuous beam properties, has great spanning capacity, less construction difficulty,vehicle body, easy maintenance, low cost advantages. So in a sharp increase in proportionof newly built Bridges in our country.Through the analysis of the development trend of continuous rigid-frame bridge at,and combined with engineering example (in san shui river extra large bridge as an example)study of safety management in construction and technology promotion, the influence of theconstruction of the issues related to the use of safe, solutions to the following safetytechnology of long span continuous rigid-frame structure of the theoretical research are putforward. Based on the research of the construction technology of long span continuous rigidframe, can be made of this kind of bridge construction technology more advanced, safe andreliable, and easier to meet the design capacity.Research on concrete can be divided into four parts: the first part puts forwardproblems--the origin of the continuous rigid frame bridge construction safety problem.Problem-the second part analysis based on the structure characteristics of the continuousrigid frame bridge, the construction technology of analyzing the characteristics of thecontinuous rigid frame bridge construction. The third part will be taken from constructionorganization, the using characteristics of continuous rigid frame bridge construction safetymanagement of technical measures are put forward. The fourth part described by specificproblem solving way choice-through engineering examples, puts forward to sometechnique to solve the problem of continuous rigid frame bridge construction safety research,at the same time describing the theoretical support of these techniques, the theory ofrationality of construction safety technology.
