Construction Technology Of Substructure Of The Cross Sea Bridge In Complex Sea Conditions

With the development of economy in our country,the demand for transportation capacity is increasing continuously.As an important part of the main road,the bridge plays a more and more important role.To the sea island,the cross sea bridge is an important way to solve the cross strait transportation.The development of the bridge has become a trend of the future development of the bridge.According to the experience on the building of crosssea bridges in history,this paper made research on theconstruction technology of substructure of the crosssea bridge in complex sea conditions.This paper in Dalian Xinghai bay cross sea bridge project as the background.First of all,the paper briefly introduces the research background,significance and research status at home and abroad.Then,according to the general situation and characteristics of the project,the engineering characteristics and the number of the main projects are analyzed and studied.Next to the Dalian Xinghai bay cross sea bridge injetty have been designed,and the jetty construction technology are analyzed.Then in Dalian Xinghai bay cross sea bridge pile foundation construction technology are analyzed and introduced the main construction methods in the pile foundation.Finally,this paper introduces the construction technology of pile cap part related to the Dalian Xinghai bay cross sea bridge.The sea is very complicated,so complex sea cross sea bridge will are different from the general water structure of the load.At the same time,the construction time of the cross sea bridge is very limited,so we need to select the construction scheme of the different type of the bridge,and put forward the most suitable plan.This paper hope that through analysis and study of construction technology of complex sea conditions of cross sea bridge substructure,and provide some help and reference for similar projects in the future.
