![]() ![]() When vertical or plumb pile groups do not provide sufficient lateral resistance the piles can be battered in order to mobilize some of the higher axial capacity to resist the lateral load. ![]() The lateral capacity of a pile is usually much smaller than the axial capacity and as a result groups of piles are often installed to increase the lateral capacity of the entire foundation system. Lateral loads come from a variety of sources including wind, earthquakes, waves, and ship impacts. Pile foundations are often required to resist lateral loading. Pile foundations are useful in regions with unstable upper soil that may erode, or for large structures. ![]() Pile foundations transfer building load to the bearing ground with the greater bearing capacity. Pile foundations consist of piles that are dug into soil till a layer of stable soil is reached. ![]()
