- The heat generated from the compressed air is gradually transferred from the inner to the outer surface of the pile section and causes temperature changes, which become smaller and slower when moving from the inner to the outer surface.
- The temperature distribution along the radius direction in a loading cycle varies with time, especially when the temperature loading starts to drop. Residual temperatures in the pile section are observed at the end of the loading cycle.
- The temperature in the pile foundation and nearby soil gradually increases with cycles because of the cumulative effect of the residual temperature. As moving from the inner surface to the outer, the increase of temperature with cycles and the temperature variation within each cycle become smaller.
- The maximum temperature in each loading cycle increases with the loading cycles but starts to be converged at a stable value after a sufficient amount of cycles. As moving from the center of the pile foundation, more cycles are needed for the maximum temperature to be converged.
- As the di increases, the section thickness of the pile foundation reduces, which requires less time for the heat transfer from the inner surface to the outer. Therefore, the temperature change in the larger di cases is more significant, but the temperature distribution along the radius direction is more uniform. The convergence of the temperature variation between cycles in the pile foundation is faster for the larger di cases.
- As the k increases and c reduces, the heat transfer speed increases, which results in larger temperature changes and higher temperatures in the concrete pile foundation. The convergence of the temperature variation between cycles in the pile foundation also becomes faster as k increases and c reduces. The effect of c is much smaller than that of k.
