Based on the layout of the water intake for the Shenzhen LNG emergency peak shaving station,combined with its functional characteristics and construction process,the water intake structure is constructed synchronously with the revetment.In view of challenges of the large size,excessive mass,and difficulty in installation due to floating transportation of the water intake structure,a targeted structural design approach is carried out.The “prefabricated floating dock + on-site secondary pouring” scheme is adopted,and numerical analysis of internal forces under different conditions is carried out.The results show that this scheme meets the design requirements.It effectively overcomes challenges encountered during the construction process and successfully passes the final inspection,achieving the goals of cost savings and shortened construction period.
