| 摘 要： | 介绍了预应力实心方桩的抗裂试验,采用有限元ANSYS软件分析了预应力实心方桩的裂缝发展和最终钢筋和混凝土的应力、应变以及挠度,验证了预应力实心方桩抗裂试验进行非线性分析的可行性,并结合预应力管桩、空心方桩进行了非线性数值分析,以研究在相同桩径条件下,不同桩型对钢筋混凝土预制桩的抗裂性能的影响,得出了预应力实心方桩的自身优势。

| Abstract: | The crack test of prestressed solid square piles is mainly introduced in this paper. The development of the deflection,the crack propagation and stress development of reinforcement bars and concrete in the prestressed solid square piles were analyzed by using the ANSYS computer program. Nonlinear analysis about the crack test of prestressed solid square pile is verified feasibility. Combining the nonlinear numerical analysis about the prestressed pipe pile and hollow square pile,to study the effect of crack resistance of different prestressed concrete pile under the condition of the same diameter,prestressed solid pile to get their own advantages. |
