Title of the articleNumerical study models piles and pile foundations under seismic loads of type
Abstract.The article presents the results of numerical studies of models of piles and pile foundations working in conditions of homogeneous and inhomogeneous soil masses under the action of seismic loads. Studies were made in the structure of the program complex Lira relation to the foundation under the Trinity compressor station. Modeling piles produced beamed finite elements on an elastic foundation. The work on the ground compressive load was taken into account by introducing a vertical compliant communication at its lower end. The results of computer calculations are compared with the results obtained by the traditional manual method. In the process of solving the problem considered the influence of parameters such computer models as breakdown structures into finite elements, the width of the zone transfer pile pressure on the soil stiffness at the base of a compliant connection. Choose the most optimal model parameters, allowing to obtain the discrepancy results from the manual method is not more than 4 %.
Keywords.pile foundation, the calculation of the single pile, seismic load, the coefficient of subgrade, computer model.
