Abstract

The application of concrete materials in poured-in-place pile engineering is extensive. Understanding the characteristics of concrete materials has a significant impact on the safe construction of poured-in-place piles. Therefore, this study investigates the evolutionary characteristics of concrete damage in poured-in-place piles using Acoustic Emission (AE) monitoring technology. The research findings reveal that concrete in poured-in-place piles mainly experiences brittle failure. The damage process can be divided into the stable deformation stage and the rapid crack propagation stage. Additionally, the point where  D = 0.20 is defined as the point of accelerated damage, while the point where  D = 0.40  is defined as the critical damage point. Furthermore, a fitting equation for the damage curve is obtained based on the exponential function, which can be used to predict the unstable failure of concrete materials in poured-in-place piles.
