Engineering Manual No. 15: Analysis of Vertical Load-Bearing Capacity and Settlement of Piles Using CPT Tests in GEO5


This fifteenth manual in the GEO5 engineering series focuses on the analysis of the vertical load-bearing capacity and settlement of piles using data from Cone Penetration Tests (CPT). The manual provides a comprehensive guide to using the GEO5 Pile CPT program, offering a step-by-step approach to analyzing single piles and pile groups according to the EN 1997-2 standard. Available for download, this manual is an essential resource for geotechnical engineers seeking to integrate CPT data into their pile foundation designs.

Learning Objective:

The goal of this manual is to teach users how to utilize CPT data in the GEO5 software to accurately assess the vertical load-bearing capacity and settlement of piles. Users will learn how to import CPT data, classify soils, and perform detailed analyses of single piles and pile groups, ensuring that their designs meet the required standards and performance criteria.

Assignment Description:

In this assignment, users are tasked with analyzing the load-bearing capacity and settlement of a single pile and a pile group using CPT data. The assignment includes importing CPT tests, classifying soils, and performing analyses according to the EN 1997-2 standard. The manual guides users through each step, from setting up the analysis parameters to interpreting the results for both single piles and pile groups.

Outcome:

Upon completing this assignment, users will be able to accurately analyze and design pile foundations using CPT data within the GEO5 software. They will gain practical experience in importing and utilizing CPT data, classifying soils, and conducting analyses that meet international geotechnical standards.

Conclusions:

The manual concludes that the vertical load-bearing capacity and settlement analysis of the pile and pile group are satisfactory when using CPT data. The manual emphasizes the efficiency and clarity of the CPT-based analysis, which is directly aligned with the EN 1997-2 standard, reducing the need for subjective soil parameter estimation.
