The time effect of the soil’s stress-strain relationship has a significant influence on the long-term settlement of pile-foundation. Long-term settlement of pile foundation includes at least two components: penetration of pile tip and compressed settlement of subsoil. By Mesri creep model
using the Mindlin stress formula to calculate the stress induced by the load of pile; and using Boussinesq stress formula to calculate the stress induced by the load of raft; a simple but practical method for predicting long-term settlement of pile-foundation was developed. The comparison between the calculated and true settlement demonstrates that this method is reasonable and useful.
