Pile foundation arrangement method of LNG storage tank
The invention discloses a pile foundation arrangement method of an LNG storage tank. The pile foundation arrangement method of the LNG storage tank comprises the steps that S1, a pile foundation is initially arranged, and the pile foundation comprises a central ring pile and multiple layers of peripheral ring piles arranged around the central ring pile at intervals; S2, the maximum bearing capacity of the pile foundation is determined according to the weight of the storage tank; S3, a bearing layer and a pile length of the pile foundation are determined according to the maximum bearing capacity of the pile foundation; S4, , the bearing layers, the distances and the pile lengths of all the layers of peripheral ring piles are adjusted according to the bearing layer and the pile length of the pile foundation; and S5, the horizontal bearing capacity of the pile foundation and the settlement of the pile foundation are checked after the adjustment is completed, and the S4 is repeated until the preset requirement is met if the preset requirement is not met. According to the pile foundation arrangement method of the LNG storage tank, the pile foundation can effectively bear the load on the upper part, so that the phenomenon that a bearing platform is stressed unevenly, and settlement or uneven settlement is generated is avoided; the pile length of the peripheral ring pile is properly shortened during the adjustment, so that the peripheral ring pile is shorter than the central ring pile, and the material cost of the pile foundation is reduced to a certain extent.
本发明公开了一种LNG储罐的桩基布置方法，包括步骤：S1、初始布置桩基，所述桩基包括中心圈桩和围绕所述中心圈桩间隔设置的多层外围圈桩；S2、根据储罐重量确定所述桩基的最大承载力；S3、根据所述桩基的最大承载力确定所述桩基的持力层和桩长；S4、根据所述桩基的持力层和桩长调节各层所述外围圈桩的持力层、间距以及桩长；S5、调节完成后验算所述桩基的水平承载力和所述桩基的沉降，若不符合预设要求则重复步骤S4，直至符合预设要求。本发明的桩基能有效地承担上部的荷载，避免导致承台受力不均匀，产生沉降或不均匀沉降的现象，且在调节时还适当的缩短了外围圈桩的桩长，使其比中心圈桩的更短，一定程度上还减少了桩基的用料成本。
