Abstract:

Estimation of the post construction settlemen is one of the most critical problems in expressway. Exponential curve method and hyperbola method is the most common method in the previous research; but the estimation results from the former model tend to be the smaller and those from the latter model tend to be larger. Based on analytical results, a kind of hyperbola model is proposed that the relationship between the settlement rate and the settlement seems as half-cube nonlinear behavior. Theoretical analysis and engineering case application prove that the estimation results of the new model are placed in those of two kinds models in common use; and they are close to the average. It is shown that the reliability of the estimation results is a little higher than the other two models.

Key words: soft ground, post construction settlement, hyperbola model, half-cube relationship
