Study on Bending Behaviors of Φ500 PHC Pile

Abstract:

Because of the smaller cross-sectional area, the flexural properties often become the controlling factor in PHC pile. Φ500 PHC is widely used as an engineering design pile in the Yangtze River Delta region. On the basis of the analysis of pile soil interaction mechanism, the single Pile under different conditions is discussed. The parameters are discussed in this article are PHC piles wall thickness, horizontal loads, bending moments, pile elastic modulus and other engineering parameters.The studies show that, the distribution of bending moment and shear is significant in 2 ~ 4m below the top surface of the pile, and after 6m, the value of them closes to 0. The main sphere of influence of the single pile bending moment and shear is concentrated at 3 ~ 4m below the top surface of the pile. Along with horizontal load enlargement, the maximum bending moment is mainly concentrated at 1.5 m below the top surface of the pile, and the maximum pile shear is mainly concentrated at 1.9 m below the top surface of the pile. Along with bending moment on the top of the pile enlarge, the maximum bending moment is mainly concentrated at 2.5 m below the top surface of the pile, and the maximum pile shear is mainly concentrated at 3.0m below the top surface of the pile. Optimize sectional area of Φ500 PHC should be selected as 0.17, and the wall thickness should be selected as 170mm.
