It’s very necessary to do research on bridge splicing method, because it must refer to splicing problems between new and old bridge during expressway widening engineering. Now there are three main splicing methods: non-splicing for both superstructures and substructures, splicing of superstructures and non-splicing of substructures and splicing for both superstructures and substructures. Now splicing of superstructure and non-splicing of substructure is used more than other two splicing methods. Each splicing method has several different new construction technologies and their aims are to decrease the splicing disease. At present our country has accumulated lots of splicing engineering experience, so the following engineering should assimilate former experience and do incessant improvement and reformation. |
