Abstract

The authors have proposed a method for evaluation of vertical bearing capacity of bored friction pile which might be capable to reflect the uncertainty of soil properties on the evaluation. The rationality of the method is examined from the application to the bridge design in this paper. A vertical bearing capacity of pile foundation is practically estimated by expressions with N-value, in which there are two kinds of uncertainties which depend on the N-values at the estimation points and the coefficient of the bearing capacity expressions. It is, therefore, necessary to improve the accuracy in estimating the bearing capacity that spatial distribution of N-values in the ground are predicted with a high accuracy and in-situ loading test results are reflected in the bearing capacity expressions.

Evaluation of Bearing Capacity of Friction Pile Based on Uncertainty of Soil Properties

St. Louis, Missouri

The authors have proposed a method for evaluation of vertical bearing capacity of bored friction pile which might be capable to reflect the uncertainty of soil properties on the evaluation. The rationality of the method is examined from the application to the bridge design in this paper. A vertical bearing capacity of pile foundation is practically estimated by expressions with N-value, in which there are two kinds of uncertainties which depend on the N-values at the estimation points and the coefficient of the bearing capacity expressions. It is, therefore, necessary to improve the accuracy in estimating the bearing capacity that spatial distribution of N-values in the ground are predicted with a high accuracy and in-situ loading test results are reflected in the bearing capacity expressions.
