ABSTRACT
Piled foundation is referred to a system of piles arranged under a structure, consisting of individual piles, strips and clusters. In order to reduce the settlement of piled foundation and to make better use of the pile material it is recommended that piles be driven to relatively dense soils. Piled strip footings are constructed under walls of buildings and extended structures. The technology of pile production in soil depends on soil conditions and the required bearing capacity of soil. Large-diameter piles, shells, and piled pillars also belong to the category of piles cast in soils. In the production of piles, large-diameter piles, and piled pillars, which are all referred to as piles for brevity, the phenomena occurring in the soil body removed to produce cast-in-place piles largely depend on the technology of pile production. Piled foundations consisting of friction piles are designed additionally by the second group of limit states.
