Soil disturbance and excess pore water pressure generation, induced by dynamics and transient excitations such as pile driving, seismic loading, and impact effects, can significantly degrade the geotechnical strength and stiffness. Given the critical importance of axial capacity in sustaining superstructures, it is essential to recognize and mitigate potential damages. This research investigates the piles reduction of axial capacity through CPTu records, which offer rapid and reliable data. Aiming to quantify the consequences of soil sensitivity and excess pore water pressure, a comprehensive dataset has been compiled comprising CPTu and pile performance records from 11 diverse sites worldwide, focusing on soft and loose deposits. The research identifies problematic sublayers and, by incorporating an analytical approach, evaluates the intact and reduced shaft and toe resistance through three distinct methods. Results indicate a substantial reduction in bearing capacity due to dynamic loading on piles. Four levels of capacity loss concern are recognized quantitively. Through case studies, the response of the problematic deposit under dynamic loading is more apprehended, conforming with the findings. The current research addresses and emphasizes the necessity of realizing pile dynamics and problematic deposit interaction. It can lead to safe, reliable, and optimal design practices based on a comprehensive understanding of soil-pile interaction.
