    摘   要
    仓库的荷载为150kN/m2,弯矩为250kN•m,水平力为100kN。仓库为一层框架结构,长48.74m,宽18.48m。工程安全等级,场地等级,地基等级均为二级。场地地面标高在2.68~3.21m之间,相对高差为0.53m,原为农田,现已整平。场地内没有地表水系存在,场地西有一小河,水面标高为0.8m。根据地形勘察报告、上部结构设计图和荷载分布,初步选择沉管灌注桩基础,柱下独立基础和CFG(Cement fly-ash gravel)桩基础三种形式。经过方案论证,从技术上的可行性、经济上的合理性、工程的可靠性三方面综合考虑,最终决定选用柱下独立基础。基础埋深为2m,高为1m,分上下二阶,上阶高400mm,面积为1.5×1.5m2,下阶高为600mm,面积为3×3m2,混凝土保护层为40mm,变阶处ho为560mm,采用C15混凝土,Ⅰ级钢筋,配筋为 。承台下有一15mm厚的C15混凝土垫层。

    Abstract
    Storehouse of rice and oil is located in the town of Chui Jiang in Ning Hua ,on the crossing street of Ma Yun and Jin Feng. It is convenient for transportation, storehouse is capacity of bearing is 150kN/m2. Carving moment is 250kN•m and the vertical is 100kN. The safety level of construction is three, and the site, foundation level is two The site of construction height is the range of the 2.68~3.21 meter. The disparity of height is 0.5m. There was irrigate, but now is painted. The under ground of the site hasn’t the water exist. The river located the west of the site. The height of water is 0.8m. The design and arrangement capacity of bearing the up ground, construction firstly choosing vibro pile foundation, CFG pile and individual footing as the foundation treatment after the calculation and analysis form the economical and reliability of technology, in addition, the safety of structure. Finally, the individual footing as the best choice storehouse is the frame of structure the length is 48.74m, wide is 18.48m. The depth of foundation is 2m, the height is 1m. Which have two steps, the up step’s height is 400mm, the site is 1.5×1.5m2. The down step is 600mm and 3×3 m2,and the concrete protection is 40mm. The change of step height is 560mm. Using C15 concrete, Ⅰlevel steel. The arrangement of the steels is  . There is have the fitted stratum which thickness is 15mm under the bearing plan.
    Keywords: storehouse   vibro pile foundation  individual footing  CFG foundation
