Friction piles spread out the load of the building vertically, allowing much more of the underlying soils to be used to support the structure without becoming overwhelmed.

摩擦桩垂直分散建筑物的荷载，允许更多的底层土壤用于支撑结构， 而不会被压垮。

The Millennium Tower's foundation consists of a 10-foot or 3-meter-thick concrete slab supported by 950 concrete friction piles driven into the subsurface to a depth of about 80 feet or 24 meters.

千禧塔的地基由 10 英尺或 3 米厚的混凝土板组成，由 950 根打入地下约 80 英尺或 24 米深度的混凝土摩擦桩支撑。
