Analysis of the accuracy of CPT and leading parameters methods to determination of the pile bearing capacity

Abstract

Abstract The paper presents a comparison of various methods used to calculate the bearing capacity of columns and the results of static loads. In the first part of the article, the methodology for the calculation of the load bearing capacities based on CPT static probes and using leading parameters are presented. Next, the investment and the hydrogeological conditions in which the columns were made are described and then subjected to test loads. The results include a summary of the dependence of the length of the columns on their load bearing capacity calculated with three methods for two different CPT sounds. A comparison of the results of calculated settlement of the column head depending on the amount of force applied to them and the results from static loads is also provided.
