Under the new situation and new requirements of LNG terminal construction in China,this paper analyzes and calculates the berth length of LNG terminal by using specifications and software,and verifies and evaluates it by mooring physical model test,referring to the actual design case of a large LNG terminal and land area along the coast of Shenzhen.Based on the analysis of the current situation and natural conditions,the optimization scheme of land formation was put forward,and the rationality of the optimized land formation was verified by means of tidal flow and sediment numerical model test analysis,while a systematic analysis was conducted on the elevation determination of land reclamation.The analysis and solution of the above graphic design key points and technical problems can provide reference for similar LNG terminals and land formation projects.
