Особливості роботи пальових кущів з коротких паль за даними числового моделювання

Abstract

There are many controversial issues when designing a new pile foundation. One of them is the difference between short piles and long piles. Research in the position, the load, which is a pile foundation, is partly transferred to the grid, and partly - on the pile and does not always have the possibility of a finger in the pile foundation corresponds to the failure of a single pile.

Complex numerical studies of the calculated model of the columnar pile foundation with the help of Plaxis software package depending on the geomet-ric parameters (length and number of piles) were carried out. The pitch and number of piles were varied at constant grid sizes. Variants of short and long piles, as well as soil environment sandy and clay soils are considered. The stages of realiza-tion of bearing capacity of piles and grid in the composition of the pile foundation for piles of different lengths were analyzed.
