摘要
通过现场抗拔静载试验和ADINA非线性结构分析程序建模计算研究竹节桩抗拔荷载传递机理及承载性能.采用ADINA非线性结构分析程序建立了竹节桩三位实体模型,并与现场实测资料对比,验证所建模型的合理性.通过该模型对竹节管桩抗拔承载力影响因素进行了分析,结果表明竹节宽度及竹节间距对竹节管桩的抗拔承载力将产生较大影响.
mA series of field test and finite element analysis software ADINA were used to study the mechanism of the nodular pile under uplifting. The finite element analysis software ADINA was also applied to establish three dimensional calculation models of nodular pile, the feasibility of three dimensional calculation model is able to be assessed by a comparison with existing methods. The influencing factors of the uplift capacity of nodular piles are studied by this model, it shows： the uplift capacity of nodular pile is sensitive to the nodular width and spacing.
