Define Axial load Capacity?

The axial capacity is largely dependent on the shaft friction developed between the conductor walls and the soil. No end-bearing resistance is considered. The overall axial capacity is equal to the initial capacity immediately after installation plus added components arising from soil restoration set-up time.
