This study presents a novel method for accurately detecting the effective prestressing of 1860-grade steel strands in existing prestressed concrete bridges through a micro-hole release technique. Researchers developed a drilling model using Solidworks and Abaqus to analyze how various parameters, including drilling depth, diameter, deflection angle, and distance from the hole edge, affect strand stress release. The findings demonstrate a direct correlation between stress relief and both hole depth and diameter, while an increase in aperture size leads to a decrease in stress alleviation. Additionally, the study compares stress release under two conditions: P-T (paste strain gauges applied first, followed by tension) and T-P (tension applied first, then paste strain gauges), revealing that the T-P condition aligns more closely with finite element simulation results. This research emphasizes the critical need to control drilling parameters to ensure measurement accuracy and introduces a mathematical equation that correlates strand tension with release strain, serving as a valuable tool for evaluating the prestressing of steel strands in bridge construction. The study concludes with recommendations for further research and practical applications in real-world engineering contexts.
