某LNG接收站取水泵房地下结构设计

Design of Structure under Water Intake Pump Room of LNG Terminal

天然气是一种优质、高效、清洁的低碳能源。为满足LNG接收站对取水泵房建设需要,本文从泵房位置选择、结构选型、暗涵穿堤结构研究、沉井下沉稳定分析、沉井井壁土压力确定、取水流态与结构安全的平衡等方面论述了取水泵房地下结构设计关键技术问题及解决方案;并以某LNG接收站取排水工程为例进行相关工程设计、提出施工控制要点,为水运行业取水泵房地下结构设计提供一种新思路。

Natural gas is a high-quality,efficient,and clean low-carbon energy source.In order to construct the water-intake pump room of LNG terminal,key technical issues and solutions to the design of the structure under the water intake pump room are discussed from the aspects of site selection,structural patterns,the research on the concealed culvert going through dike,the stability of sunken well,the determination of soil pressure acting on the wall of sunken well,and the balance between water-intake flow state and structural safety.Based on the water-intake and drainage works of a LNG terminal,the construction control essentials are proposed during the engineering design,which will provide a new approach for the design of underground structure of water-intake pump room in waterway transportation industry.
