The invention relates to the field of
geotechnical engineering, in particular to an evaluation
processing method for entrainment superimposed settlement of
pile groups. According to the method, by utilizing a
solid deep foundation simplified calculation model, a calculation formula for stress fields of surrounding soil bodies of
pile foundations is deduced, and from the analysis of the calculation of the settlement of the
pile foundations to the calculation of the stress fields and displacement fields of the surrounding soil bodies of the pile foundations, the evaluation
processing method for the entrainment settlement of the pile groups is formed, and meanwhile, the entrainment settlement calculation of a single pile group foundation can be expanded to the entrainment settlement calculation of multiple pile group foundations by using the method. The evaluation
processing method for the entrainment superimposed settlement of the pile groups provided by the invention has the advantages that the stress fields of the surrounding soil bodies of equivalent
pier foundations are completely deduced; a method of classical
soil mechanics is introduced into the evaluation method for the entrainment settlement of the pile groups, and therefore, not only can the settlement of pile tips be evaluated, but also the entrainment superimposed influences of the pile group foundations on the surrounding soil bodies can be evaluated. The evaluation processing method for the entrainment superimposed settlement of the pile groups is clear in concept, simple in method and reliable in evaluation accuracy, and convenient for
engineering application.
