A Study on PHC Pipe Pile Spur Dikes Three-Dimensional Finite Element Numerical Modeling in the Lower of Yellow River
Based on the analyses of the traditional rockfill groins of spur dikes，the PHC pipe pile groin is presented.The functions of the riverwall protection function, anti-erosion performance, and structure design of the groin were analyzed. By the three-dimensional finite element numerical modeling, when the scour depth of spur dike is 20m, the safty coefficient of spur dike is 1.21 and the maximum deformation is 1.3 centimeter. The studies are shown that the PHC pipe pile have high strength, stability and anti-erosion performance; The deign of double-row pile is applied to the head of spur dike where the displacement is maximum and improves stress boundary condition of the spur dike and improves the whole stability effectively.
