摘要
根据９个试件的试验结果，分析了钢纤维混凝土三桩厚承台的破坏模式与传力机理。表明钢纤维混凝土三桩厚承台的破坏为角桩冲剪破坏，认为传为模式宜采用空间桁架模型。根据该模型给出的钢筋拉杆拉力及钢筋用量计算公式可供工程设计及进一步研究参考。
According to the test of 9 specimens,a failure model and load transfer mechanism of steel-fiber reinforced concrete(SFRC)thick pile cap with three piles is analysed.The results show that the cap has experienced punching iailure with a conner pile.The load transfer model should be a space truss model.The formula for calculating the tension and quantity of steel on the basis of the model are useful in engineering design and further study.
