If a building is anchored into the ground, it C. is built on a solid foundation and unlikely to shift. Ground anchors are metal bars inserted into drilled holes in a slope. They function by transferring a horizontal load on a retaining wall back to the ground, fixing the foundation into the ground. This is useful to hold a structure in place in case of an earthquake.
