To provide an underground tank structure capable of reducing temperature load applied to a tank skeleton.SOLUTION: An underground tank structure 1 stores low-temperature liquefied gas such as LNG, and has a tank skeleton comprising a bottom slab 5 and a side wall 7, wherein the bottom slab 5 is divided into two layers of an upper layer bottom slab 5a and a lower layer bottom slab 5b. The upper layer bottom slab 5a is connected to the side wall 7, and the thickness of the upper layer bottom slab 5a is substantially identical to that of the side wall 7. The underground tank structure 1 is configured such that a frost line b indicating a position showing 0°C with utilization of a tank is managed at a position so as to become substantially the same separation distance from an inner surface of the tank skeleton at the side part and bottom part of the tank skeleton.SELECTED DRAWING: Figure 1
【課題】タンク躯体に加わる温度荷重を低減可能な地下タンク構造を提供する。【解決手段】地下タンク構造１はLNG等の低温液化ガスを貯留するものであり、底版５と側壁７を含むタンク躯体を有し、底版５は、上層底版５ａと下層底版５ｂの２層に分けて設けられる。上層底版５ａは側壁７と連結され、上層底版５ａと側壁７の厚さが略同一である。地下タンク構造１では、タンク稼働に伴い0℃となる位置を示す凍結線ｂが、タンク躯体の側部と底部においてタンク躯体の内面から略同一の離間距離となる位置に管理される。【選択図】図１
