Introduction

The broad variety of pile types and fabrication methods, depending on the pile-soil interaction mode, include either soil extraction or soil displacement. Although piles are applied everywhere, the current foundation engineering practice faces many issues of pile bearing capacity evaluation.

As compared with precise but expensive in-situ methods that require special equipment, the methods for pile bearing capacity analysis do not demonstrate adequate compatibility with real data, especially for soil displacement piles. The engineering method [1] based on correlations of design resistances and soil physical properties is far from perfect either.

This paper presents an analytical model for pile installation into a leader hole. The authors did their best to make the model valid so that the model input parameters and relationships would be a part of the on-site geological survey report.

The known pile analysis techniques consider a pile as just being in soil with no data on how the pile got there and what changes in the soil characteristics could happen. Therefore, it is necessary to develop an analytical model for a rigid pile forced into a plastically compactable soil. Among current publications on the analysis of pile (probe) penetration into soil, the paper by Fedorovsky and Grevtsev [2] should be mentioned.
