Abstract:Aiming at the problem of how to effectively utilize the original terminal structure in the upgrading and reconstruction project of high pile wharf,based on the phaseⅠcontainer terminal renovation project in Luojing port area of Shanghai Port,the principles and key issues of comprehensive utilization of the original terminal structure are put proposed.The compliance of the original structure with existing specifications,the judgment method of remaining service life,and the treatment method of the interface between new and old concrete are analyzed and studied.This paper proposes a comprehensive solution to the problems of general layout,process,and hydraulic structure during renovation,and lists multiple feasible technical routes for utilizing the original structure during renovation.The general conclusions are that it is advisable to mainly review the structural construction requirements according to the design specifications of the current year,and the remaining life of the structure should be determined through testing and evaluation.The project willThree original wharves are arranged in the plan layout at the location of the less loaded driving channel,and lightweight equipment is used to reduce the load on the quay crane by about 20%.Through practice,conventional construction methods can be used to achieve technical routes such as dismantling and rebuilding the original structure,reinforcing the original structure with supplementary pile foundations,raising the dock elevation by 0.2-1.6 m,adding scaffolding and replacing panels to the approach bridge,and constructing new water and electricity pipeline routes under the original structure.
