註釋The techniques outlined in this guide apply to foundation testing for overhead transmission line towers and pole structures. They are also applicable to telecommunication towers. The folowing modes of applied loadings are considered. (a) axial (vertical, either in uplift or compression; (b) lateral (horizontal) shear, including those which give rise to high overturning moments; (c) combined axial and lateral loads. Only static monocycle or multicycle loadings are considered in this guide. In this context a cycle is defined as a complete loading stage from an unloaded state, through a series of load increments and back to an unloaded state.
