摘要:

通过对预应力管桩PHC500AB(100)抗弯试验,研究管桩受弯作用下桩身裂缝出现、开展情况及变形特征,分析其承载能力及破坏特征.试验研究表明:预应力管桩PHC500AB(100)满足规范要求检验标准,具有较高的安全储备,但当桩身出现裂缝后截面刚度损失较大,对抗弯性能较为不利.

Abstract:

Through the bending test of PHC500AB(100) prestressed pipe pile, the occurrence, development and deformation characteristics of pile cracks under bending of pipe pile were studied, and its bearing capacity and failure characteristics were analyzed. The test results show that the prestressed pipe pile PHC500AB(100) meets the standard requirements and has a high safety reserve, but when the pile body cracks, the section stiffness loss is large, and the bending performance is unfavorable.
