This sixteenth manual in the GEO5 engineering series is focused on the analysis of the horizontal bearing capacity of a single pile using the GEO5 Pile program. The manual guides users through the application of the p-y method for modeling the pile as a beam on an elastic Winkler foundation and compares various methods for calculating the modulus of subsoil reaction. Available for download, this manual is an essential resource for geotechnical engineers who need to assess the lateral load-bearing capacity of piles.

Learning Objective:

The goal of this manual is to teach users how to analyze the horizontal bearing capacity of a single pile using the GEO5 software. Users will learn to apply the p-y method, set up the necessary soil parameters, and evaluate the impact of different calculation methods for the modulus of subsoil reaction on the pile’s horizontal capacity.

Assignment Description:

In this assignment, users are tasked with analyzing the horizontal bearing capacity of a single pile using the p-y method in GEO5. The analysis includes setting up the problem based on previously defined vertical load conditions, selecting different methods for calculating the modulus of subsoil reaction, and assessing the pile’s horizontal displacement, internal forces, and reinforcement requirements.

Outcome:

Upon completing this assignment, users will be able to accurately assess the horizontal bearing capacity of a single pile using GEO5 software. They will gain practical experience in applying the p-y method, comparing different subsoil reaction models, and ensuring that the pile design meets the necessary structural and serviceability criteria.

Conclusions:

The manual concludes that the choice of method for calculating the modulus of subsoil reaction has some influence on the internal forces and deformations observed along the pile, but the overall impact is not significant. The results confirm that the pile design is satisfactory across all tested methods, providing a robust approach to assessing lateral load capacity in geotechnical projects.
