On the Calculation of Groups of Piles Using Mutual Influence Coefficients in the Elastic Half-Space Model

Abstract

The existing methods of calculating pile foundations from the standpoint of degree of detail, accessibility, and computing speed are discussed. The basic mutual influence functions of piles for performing calculations by the method of mutual influence coefficients are examined. An improved influence function is proposed and practical recommendations are made for performing calculations by this method. Calculations and a comparison of the results are presented for pile groups ranging in size from 4 to 1296 piles in the elastic half-space model by the method of mutual influence coefficients and the method of finite elements.
