Title of the articleBearing capacity and settlements of plate-pile foundations under cyclic loading
Abstract.Under current conditions in the construction of buildings and structures trend of increasing loads on the foundation ground and the use of weak soils as a foundation contributed to the fact that one of the common ways to increase the load-carrying capacity and reduce sediment, is the use of plate-pile foundations. These foundations and basements are exposed to both static and cyclic loads, which in some cases are primarily determined during the safe operation of buildings and structures. The question of influence of cyclic loads on the behavior of combined plate-pile foundations is studied not enough. In connection with this carried out experimental and theoretical studies of plate-pile foundations under cyclic loading. Developed calculating method of the plate-pile foundation settlements under cyclic loading, considering joint deformation of ground base, piles and plate grillage. Depending on the loading cycle, cyclic loading leads to a redistribution of load between the elements of plate-pile foundation, the ground base at different levels of the plate grillage and the ground massive at space between piles. This calculation method takes into account the changes in the stress-strain state of the plate-pile foundation elements and shows good agreement between the calculated and actual values of the researched parameters.
Keywords.plate-pile foundation, weak ground, cyclic loading, base settlement, tension, stress, ground space between piles, calculation model.
