Abstract:To improve transportation efficiency,reduce logistics transportation costs,increase transportation safety and ensure cargo quality,and make rational use of limited shoreline resources,it has become more and more common for ports to convert bulk cargoes originally transported in bulk to container transportation in recent years.To ensure the safety and normal operation of the wharf structure after reconstruction,the existing wharf usually needs to first assess and grade the damage conditions,then repair and strengthen the original structural components before further reconstruction and expansion into a container terminal.In the process of wharf design,it is necessary to select and compare the reinforcement and reconstruction schemes commonly used in engineering,put forward a set of clear,safe and practical technical path for wharf reinforcement and reconstruction,systematically match the damage types of complex old wharf with the repair and reinforcement scheme,form the technical requirements that can be promoted and provide clear,complete,safe,applicable and highly implementable technical requirements for construction.According to the different damage conditions of the original wharf structure,such as crack closure,damage repair,structural component reinforcement,pile foundation repair and so on,phaseⅠcontainer terminal renovation project in Luojing port area of Shanghai Port has formulated the corresponding repair scheme.It provides technical reference cases and reusable engineering experience for the repair and reconstruction of high-pile beam and slab wharfs in other regions.
