| 摘 要： | 为研究PHC-TSC高强组合桩的受力性能,利用ABAQUS建模对比分析了PHC预应力高强混凝土管桩、TSC高强混凝土薄壁钢管桩、PHC-TSC高强组合桩的单轴受压过程,得到了各自的应力应变曲线和极限抗压强度,结果表明PHC -TSC组合桩的承栽力比PHC和TSC单独作用的叠加有显著提高.

| Abstract: | PHC pre-stressed high strength concrete tube pile,TSC high strength thin-steel-tube pile,and PHC-TSC high strength composite pile are compared and analyzed utilizing ABAQUS,in order to study the mechanical behavior of PHC-TSC high strength composite pile.Their stress-strain curves and ultimate compression strength are obtained,which indicate that the strength of PHC-TSC composite pile is quite higher than the combined strength of PHC and TSC.References are provided for further study on its mechanical perfor... |
