Forecast of settlement of single pile based on hereditary creep

Abstract

The various calculation models are proposed in the literature for the purpose of description the creep behavior of soil bases. The objective of the paper is to develop an algorithm to predict long-term settlement of piles based on the rheological deformation model using Koltunov's creep kernel. The paper discusses the results of single pile tests on weathered claystones and sandstones. Based on experimental results and theoretical study the author developed an automated algorithm for the calculation of settlement of pile on weathered claystones and sandstones. The following tasks are solved: 1) to describe the research technique; 2) to analyze the results of testing single piles; 3) to perform numerical calculation of settlement of piles; 4) to describe the capabilities of the developed algorithm for the calculation of pile settlement; 5) to compare the results of field tests, numerical simulation and calculation of the proposed method; 6) to state conclusions. The result shows that the proposed method is an excellent option for identifying the parameters of creep core for the prediction of long-term settlement of piles on claystones and sandstones.
