摘　　要：运用灰色系统理论对钢钎维钢筋混凝土二桩承台进行关联分析。基于已有的实验数据和成果,研究其极限承载力的影响因素及各自对极限承载力影响的重要性程度;根据关联度的大小分析提高承台极限承载力的方法,为经济有效地设计钢钎维混凝土桩承台提供理论依据。Grey relational analysis on two-pile Steel Fiber Reinforced Concrete (SFRC) caps is matce out in this paper. Based on existing date and results of those experiments, the main effective factors on ultimate bearing capacity of SFRC caps are affirmed and their importance is studied by their relation index, and further, methods of how to improve the bearing capacity of caps are proposed. The conclusion in the paper offers theory evidence for designers' to design caps economically and effectively.
