摘要
分别采用GB 50010—2010《混凝土结构设计规范》附录E和预应力混凝土管桩国标图集10G409中的方法对复合配筋预应力混凝土桩桩身的正截面力学性能进行了设计计算,并与抗弯试验结果进行对比分析,提出了适用于该类型桩桩身正截面承载力的计算方法。并结合预应力混凝土管桩和复合配筋桩桩基础上节桩的水平承载力对比试验,对复合配筋桩在地震荷载作用下的基本性能做了初步探讨。
The normal section bearing capacity of pretensioning prestressed composite reinforced concrete （PRHC） pile body are designed by the calculation method of Appendix E of GB 50010-2010 ＂Specification for design of concrete structures＂ and National Standard Design of Prestressed Concrete Piles 10G409. The two kinds of calculation values of the bearing capacity are compared with the bending test results under the same condition, and the best calculation method for normal section bearing capacity of PRHC pile body is put forward. In addition, according to the test results of horizontal bearing of pile foundation respectively using PHC piles and PRHC piles as top pieces, the basic performances of PRHC piles under the condition of earthquake load are preliminarily discussed.
