Effect of the degradation of concrete friction piles exposed to external sulfate attack on the pile bearing capacity

An analytical method is proposed in this paper to present the effect of the degradation development of concrete friction piles subjected to vertical loads on the pile bearing capacity. This paper proposes an analytical solution of the sulfate diffusion-reaction equation based on Fick's law and Danckwerts' method in polar coordinates. A chemo-mechanics model is established to compute expansion based on the consideration of the pore filling....
