| 摘 要： | 预应力混凝土管桩在水平地震作用下,管桩与桩帽接合部承受较大的弯矩作用,易发生弯曲破坏.本文采用非线性有限元方法,对2根预应力混凝土管桩试件的受弯承载力进行了模拟分析,并将分析结果与试件的试验结果进行了对比分析.分析结果表明,所建立的计算模型是合理可行的,计算分析结果与试验结果吻合较好.

| Abstract: | Under horizontal earthquake action,the jointed region connecting the prestressed concrete pipe pile and the base platform is subjected to a significant bending moment,and bending failure often occurs consequently.Utilizing the nonlinear finite element procedure,bending-carrying capacity of two prestressed concrete pipe piles was simulated.Comparison between the analysis results and the experimental ones indicated that the former have a good agreement with the latter,thus proved that the computational model is reasonable and practicable. |
