Concise Edition: Pile Foundation Basics

2.2. Factors of Pile Foundation The use of pile as one of the important elements in the construction of a structure has long begun in the history of civil engineering in the world. Piles are used as supports and tools to move loads from the structure to the ground.

Pile use is due to: 1. The existence of a suitable bearing layer could not be obtained. The soil under the structure is not functioning well or in other words is unable to bear the load caused by the structure when the shallow foundation is used.

2. The compressibility of soil causes great sedimentation when the shallow foundation is used.

3. The distribution of soil beneath the surface is not uniform.

4. For the purpose of preventing the action of gravity from beneath the surface such as hydrostatic action.

5. To obtain a strong strata in the excavation work.
