| 摘 要： | 将钢纤维混凝土应用于桩基承台中,有利于提高承台的受力性能.但对于钢纤维混凝土桩基承台特别是厚承台的传力机理目前国内外还没有形成统一的认识.为了探讨钢纤维混凝土六桩承台的受力机理,在已有的试验研究基础上,利用大型通用有限元软件ANSYS对钢纤维混凝土六桩承台建立数值模型,模拟计算了开裂荷载、极限荷载、裂缝分布、承台内部应力应变分布等,并将计算结果与试验结果进行了对比分析.分析结果表明:有限元计算结果与试验结果吻合良好;钢纤维混凝土六桩承台的传力模型符合空间拉压杆模型.图9,表3,参12. |
| 关 键 词： | 钢纤维混凝土 六桩承台 非线性有限元分析 受力机理 |

| Abstract: | Steel fiber reinforced concrete(SFRC) is used more and more widely nowadays.The capability of stress for pile-caps that includes SFRC is improved.But there is not agreements to the mechanism of SFRC pile-caps among the researchers,especially the thick pile-caps.For the sake of discussing the mechanism of SFRC pile-caps,the large general finite elemental software-ANSYS was used for establishing the model which calculated and analyzed in the aspects of cracking load,limit load,distribution of stress in caps and cracks based on experimental research,and the results of the calculations and tests were compared.The results indicate that calculation and experiments are coincided well;the model of load-transferring accords with spatial strut-and-tie model(STM).9figs.,3tabs.,12refs. |
| Keywords: | SFRC six-pile cap nonlinear finite elemental analysis load-transferring mechanism |
