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 a frost line b indicating a position showing 0°C with utilization of a tank is positioned so that separation distances from an inner surface of the tank skeleton with respect to the bottom slab 5 and side wall 7 are substantially identical to each other. The position of the frost line b is managed by circulating heat medium to heater pipes 13, 22 of the side part and bottom part of the tank skeleton, and the heater pipes 13, 22 are arranged substantially at the same separation distance from the inner surface 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、タンク稼働に伴い０℃となる位置を示す凍結線ｂが、底版５と側壁７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ある。凍結線ｂの位置は、タンク躯体の側部と底部のヒータ管１３、２２に熱媒体を循環させることで管理され、ヒータ管１３、２２は、タンク躯体の内面から略同一の離間距離に配置される。【選択図】図１
