Analysis of Influencing Factor of Super-Long Single Pile’s Effective Pile Length

Abstract:

Taking Clough & Duncan’s hyperbolic model as the transfer function, the influencing factor of super-long single pile’s effective pile length are analyzed. Discussed four kinds factors, which are the pile elastic modulus E_p, the external friction angle σ, the material parameters k₁ and the allowable settlement S_a, effect on the effective pile length. The conclusion has some active meaning to super-long single piles’ the theoretical study and the application to engineering.
