AI Technical Summary

Technical Problem

Existing methods for analyzing the vertical bearing capacity of pile foundations involve complex calculations and are inefficient.

Method used

By dividing the pile foundation nodes, the relationship between the soil side friction resistance and the soil stress at the pile bottom and the relative displacement between the pile and the soil is determined. A vertical bearing capacity analysis model for the pile foundation is constructed, the pile foundation load and pile stiffness matrix are calculated, and the PS curve is plotted to obtain the pile foundation bearing capacity.

Benefits of technology

It simplifies the calculation process, improves efficiency, is easy to operate, requires no on-site experiments, and only requires calculations based on existing data.

Abstract

This invention discloses a method and system for analyzing the vertical bearing capacity of pile foundations. The method includes: dividing the pile foundation into n nodes from top to bottom according to the soil layer distribution elevation; determining the relationship between the soil side friction τ and the pile-soil relative displacement s; determining the relationship between the soil stress σ at the pile bottom and the pile-soil relative displacement s; constructing a vertical bearing capacity analysis model for the pile foundation; calculating the pile foundation load; calculating the pile stiffness matrix; substituting the pile foundation load and the pile stiffness matrix into the vertical bearing capacity analysis model to obtain the pile-soil relative displacement; and plotting the pile foundation load-settlement P-S curve between the pile foundation load and the pile-soil relative displacement. The advantages of this invention are: simple calculation process, simple operation, and high efficiency.
