(1) The main objective is to carry out a study on the key fundamental and technical issues to developa feasible method for super-fast large-area economical marine reclamations in the Guangdong-HongKong-Macau Greater Bay Area, especially in Hong Kong.(2) To study the lateral deformation, stability, water-tightness of an impermeable FRP pile wallinstalled in seabed to enclose a reclamation area.(3) To study super-fast blow filling of local Hong Kong Marine Deposits (HKMD), self-weightconsolidation, and fast consolidation of HKMD by vertical drains with vacuum pre-loading inside animpermeable pile wall and properties and behaviour of HKMD through large-scale physical modeltests, laboratory tests, and numerical modelling.(4) To study the dispersion and diffusion as well as sedimentation of soil particles and influence onmarine environment due to dredging plus an effective protection method and marine ecosystemimpact assessment.(5) To carry out a prototype field trial of the proposed method at a selected marine site in HongKong, with field instrumentation and monitoring, which will involve the use of general soil fills andsuper-fast blow filling of local marine deposits and fast consolidation of marine deposits by verticaldrains with vacuum preloading, surrounded by an impermeable pile wall.(6) To analyze all data from the above-mentioned tests, trial, and numerical modelling to assess theperformance, advantages, and application ranges of the super-fast marine reclamation approach andpromote this approach for applications especially in Hong Kong and the Guangdong-Hong KongMacau Greater Bay Area.
