摘　　要：LNG大型低温储罐罐底保冷层具有结构设计复杂、交叉施工难度大、安装标准高的特点,在施工中要严格遵循规定的程序和技术要求,而交叉施工的安全高效、施工的质量控制和防雨、防潮等问题的解决是大型低温储罐罐底保冷工作顺利实施的重要保证。文章以国内某一16万m3LNG大型低温储罐为例,对罐底保冷层的结构特点、施工顺序、安装方法等内容进行了详细叙述。The cold-insulating layer of large-sized low-temperature LNG storage tank bottom is complex in structure design, difficult in cross construction and high in installation standard. Observance of specified procedures and technical requirements during construction, safe and effective cross construction, control of construction quality, and prevention form moisture and rain are essential for smooth implementation of cold- insulating works of large-sized low-temperature storage tank bottom. Here, with domestic one 16 × 10^4 m^3 largesized low-temperature LNG storage tank as example, the structural feature, construction sequences and installation method of the cold-insulating layer of the tank bottom are described in details.
