Accelerated development of port infrastructure in China has intensified demands for higher throughput capacity and elevated berth class standards.Parallel shifts in vessel-transported cargo types necessitate multifunctional wharf structures.To adapt to the development trend of modern ports,it is urgent to carry out renovation and upgrading of the existing aging wharfs.Wharfs with critically limited residual service life and insufficient adaptability to modern vessel dimensions or operational profiles typically require complete demolition followed by in-situ reconstruction.Taking the demolition project of coal terminal in Luojing port area of Shanghai Port as an example,this study establishes technical requirements for demolition scope delineation,dismantlement of pile-supported wharf components (beams,slabs,and piles),and dredging strategy optimization.Cost breakdown analysis of demolition methodologies provides foundational technical parameters for subsequent reconstruction.The research results can provide a reference for similar pile-supported wharf demolition projects.
