AI Technical Summary

Technical Problem

Existing methods cannot accurately reflect the dynamic evolution characteristics of bearing capacity of foundation piles due to environmental changes, load history and other factors during long-term service. Furthermore, in marine environments, it is difficult to quantify the coupled degradation effect of multiple damage mechanisms on bearing capacity, and it is impossible to update the dynamic changes of bearing capacity under random extreme events in a timely manner.

Method used

By constructing a dynamic update mechanism based on pore pressure static cone penetration test data, and combining finite element analysis and damage sensitivity coefficient, a multi-mechanism coupled damage dynamics model is established to monitor and update the vertical ultimate bearing capacity of the foundation pile in real time, including the effects of cyclic load, horizontal load, scour and corrosion damage mechanisms.

Benefits of technology

It enables real-time dynamic updating of the ultimate vertical bearing capacity of foundation piles, overcomes the limitations of static assessment in traditional methods, quantifies the coupling effect of multiple damage mechanisms, responds promptly to the impact of extreme events such as ship collisions and earthquakes, and improves the safety assessment capability of wharf structures.
