摘要
首先开展了PHC管桩现场水平静载试验,获得了单桩水平临界荷载和极限承载力。结合FLAC3D建立了考虑混凝土和钢筋共同作用时的PHC管桩模型,对单桩水平受荷下桩土相互作用进行了数值模拟,并与实测结果进行了对比分析,验证了该模型的合理性。最后讨论了PHC管桩在水平受荷时的受力与变形特性。研究成果可为PHC管桩水平承载工作性状提供研究基础。
The field horizontal static load tests of PHC pipe were carried out,and the horizontal critical load and ultimate bearing capacity of single pile were obtained.Combining FLAC3D,a non-uniform PHC pipe model considering the interaction of concrete and steel bars was established.The pile-soil interaction under horizontal loading of single pile was simulated numerically,and the rationality of the model was verified by comparing with the measured results.Finally,the mechanical and deformation characteristics of PHC pipe under horizontal load were discussed.The research results can provide a basis for the study of the horizontal bearing behavior of PHC pile.
