Abstract: When an impact source is applied to the top of a pile, the waves near the top exhibit strong three-dimensional characteristics. When an anomaly is locally distributed near the top of the pile (shallow anomaly), there are ...

Abstract: One-dimensional stress wave theory is widely used to analyze quantitatively the reflections in low-strain integrity testing of piles. However, a point or disk loading produces body and Rayleigh waves near the pile top. The ...
