A case of analysis and selection of the bearing capacity value of bored pile

Abstract

The content of the article is the results of analysing and evaluating the bearing capacity of bored pile according to laboratory and in-situ test results to draw conclusions about the reliability of the calculation methods. The calculated results are compared with the test results using Osterberg compression box of bored piles with diameter D1500 and length 85 m. The analysis results show that the bearing capacity of the pile calculated according to the standard penetration results of the Japanese Institute of Architects 1988 and the pressuremeter test of Bustamante Gianeselli 2006 has a value consistent with the pile static loading results. The law of changing the frictional resistance according to the calculated results based on the pressuremeter test is consistent with the analysis results from measuring the deformation along the pile body. The content of the article can be useful in choosing a reliable method to evaluate the bearing capacity in design of long piles.

Keywords: Bearing capacity of bored pile; pressuremeter test.
