【摘要】 通过 30个缩尺比例为 1∶5的钢纤维混凝土二桩厚承台模型试验研究 ,系统地分析了影响钢纤维混凝土二桩厚承台极限承载力的主要因素 ,并应用最小二乘法给出了钢纤维混凝土二桩承台极限承载力的计算公式。与普通钢筋混凝土承台相比 ,其极限承载力有较大幅度的提高。更多还原

【Abstract】 Through an experimental research on thirty specimens of steel reinforced concrete and steel fiber reinforced concrete (SFRC) two-pile thick cap of 1∶5 model ratio, the main factors that influence the ultimate bearing capacity of SFRC two-pile thick cap are analyzed systematically.The calculation formula of the ultimate bearing capacity of SFRC caps is developed by method of the least-square. By comparing with common reinforced concrete thick caps, their ultimate bearing capacity is raised remarkably.更多还原
