Design Technology of Drainage Closure Gap for Sea Reclamation Project in Strong Wave Area During Construction Period
Drainage closure gap is an important structure in the construction of large-scale sea reclamation projects,thus its reasonable design plays a key role in dredger-filling work.Based on a large-scale sea reclamation project in the Mediterranean region,which is seriously affected by waves,a finite element method was used to analyze the situation of wave field under 6 working conditions,which produced the law of wave height distribution and the related influence on the selection of closure gap location.And then the optimum location was determined by referring to the field construction organization.The structure of drainage closure gap was designed and verified from the aspect of stability.Furthermore,a local scouring calculation of the closure gap was carried out,and a scour shielding proposal was proposed subject to higher risk of scour,which could provide a reference for similar projects.
