Analysis on Bridge Dismantling Technique of Shanghai Wusong Road Watergate Bridge in

For example of Shanghai Wusong Road Watergate Bridge Dismantling Project, the paper introduces the reason to select the mechanical dismantling method, the detail application of chain saw cutting method, sheet saw cutting method, gas cutting method and hammer machine chiseling method, and the security principle, opposite principle, symmetrical balance principle and the principle of breaking up the whole into parts carried out in the dismantling. The paper specially analyzes five kinds of structure dismantling technologies and gist, and proposes the controllable mechanical dismantling method firstly to be used for the bridge dismantling in the central areas of big cities and the view of carrying out four dismantling principles, which can be referred for the same projects.
