填芯与非填芯管桩纵向振动特性数值模拟对比

Comparative analysis of numerical simulation of longitudinal vibration characteristics of core filled pipe pile and non-core filled pipe pile

针对填芯管桩与非填芯管桩,采用ANSYS软件分别建立二者的纵向振动数值模型,将填芯高度和填芯纵向剪切波速两个因素纳入研究范围,通过求解器得出(非)填芯管桩桩顶的速度时域曲线,对填芯管桩与非填芯管桩的纵向振动特性进行对比分析,进一步明确填芯管桩与非填芯管桩动力响应规律与差异。

For both core-filled pipe piles and non-core-filled pipe piles,ANSYS software was used to establish the longitudinal vibration numerical models of the two,and the two factors of core-filling height and core-filling longitudinal shear wave velocity were included in the research scope and obtained by the solver(Non-)The velocity-time curve of the top of the core-filled pipe pile,the longitudinal vibration characteristics of the core-filled pipe pile and the non-core-filled pipe pile are compared and analyzed to further clarify the dynamic response laws and differences of the core-filled pipe pile and the non-core-filled pipe pile.
