Study And Analysis On Redistribution Of Internal Force During Bridge Construction

Domestic has started to construct the suspension bar arched bridge since on century 70's, At present this type bridge quite popularized, Afterwards domestic massively constructs the diagonal cable bridge, the hanging bridge and so on has the flexible component of structure. This enables by the suspension bar arched bridge the work which diagnoses for representative's this kind of project examination and the structure damage diagnosis and prevents and controls to obtain the more and more attention The structure passes through the long-term use unavoidably to be able to have various damage In the history,there was the structure to suffer injury the example which so that the project collapses, also has caused in the economical losses, also brings the huge disaster to the humanity In the recent two years domestic suspension bars arched bridge also many times has the accident.The reason is various,has the use maintenance does not work as, the traffic accident or the human error accident, the environmental factor and so on Also possibly has in the computation theory and the design method insufficiency.Based on referring and summarizing other already exited the literature studies and, this article did to the bridge suspension bar load behavior and its the secure design has been thorough the system research by myself personally experience the hefei ShouChun bridge trades work and so on rope design, construction as well as monitor.Analyzed the suspension bar wearily to destroy the mechanism, the suspension bar and cable the damage reason,Elaborated the suspension bar health monitor content and the method Proposed the suspension bar replaces the structure examination and the craft proof, and applies these viewpoint attempts to the project is actual.
