Caofeidian reclamation engineering is characterized by fine grain and long blowingdistance ,and the production capacity is low.In order to improve the construction productivity and reduce the construction cost,we analyze the CSD mining and transport data,and mud pump cavitation point to study the optimization of the construction technology.By the optimized construction technology,the construction productivity of Caofeidian reclamation land reclamation project is increased by 15%,the construction cost is cut down and the construction period is shortened.
