摘　　要：针对山区填土地基上的轻钢厂房结构,本文提出了一种适应填土地基沉降的钢结构柱下浅基础,该柱基础包括连接钢筋以及从上到下依次设置的柱底板、钢垫板、预制垫块和柱下独立基础,其中连接钢筋包括顶部螺杆钢筋、中部螺杆钢筋和底部锚栓螺杆钢筋。该钢结构柱基础结构合理,施工方便,安全可靠,可以根据需要随时调节柱底高度,能有效解决地基沉降对现有轻钢厂房柱基础施工及结构正常使用所带来的不利影响,在相应的工程建设中具有良好的经济效益和时间效益。Considering the light steel factory structure on filled ground in mountainous area, this paper puts forward an shallow foundation under steel structure column which adapts to filled ground settlement. The column foundation includes connecting reinforcement and followed by column bottom plate, steel base plate, preeast block and single foundation under column from top to bottom, and the connecting reinforcement includes top screw steel bar, middle part screw steel bar and bottom anchor bolt screw steel bar. The steel structure column foundation has advantage of reasonable structure, convenient construction and safe operation. The column bottom level can be adjusted when needed. The foundation can effectively eliminate the unfavorable influence of filled ground settlement to present light steel factory structure column foundation construction and factory normal use, so it has good economic and time benefit in the corresponding engineering construction.
