摘　　要：山东LNG是国家"十一五"LNG规划的重点项目,一期计划建设3台LNG储罐。储罐底板作为混凝外罐的重要组成部分,对保障储罐安全至关重要。在总结其他LNG储罐底板方案经验教训的基础上,山东LNG对底板设计和施工方案均进行了改进,减小了底板厚度,选用C40混凝土,取消了底板环向预应力和底板上方凸台,设置了底板暗梁及施工缝企口。文章主要将山东LNG储罐底板与国内其他项目做对比,并分析其优劣。Shandong LNG is the key project of national 11th Five-year LNG plan. The first phase of this project is to construct three LNG storage tanks. The storage tank floor, as an important part of the concrete outside tank, plays the most important role in guaranteeing the storage tank＇s security. On the basis of summing up the experience of other schemes, Shandong LNG does some modifications on the floor＇s design and the construction scheme. That is, reducing the bottom thickness, selecting the C40 concrete, canceling the floor circular prestressing and the convex platform above the floor, setting the bottom dark beam and the construction seam tongue and groove. This paper will compare Shandong LNG storage tank floor with other domestic projects, and analyze its advantages and disadvantages.
