Methods for Estimating the Load Bearing Capacity of Pile Foundation Using the Results of Penetration Tests - Case Study of Road Viaduct Foundation

Abstract

Studies using static probing guarantee the precision of measurements and reliability of results which are of fundamental importance for the entire design process. More and more new modeling and calculation schemes and concepts using the direct results of static probing have been developed and still are being developed based on direct probing parameters, which is the result of a very rapid development of this approach, and increasingly more common use by designers and constructors in various research centers working in the field of soil mechanics, geotechnics and geoengineering.This paper presents the estimation of load bearing capacity based on direct parameters obtained from the results of static probing test of ground, which are mainly used in engineering in Poland and in Europe, and which form the basis for new ideas and concepts for calculation. The calculations of the reference pile foundation based on the results of the actual study conducted for the road overpass in the expressway currently under construction near Miłomłyn town in Warmia-Mazury province are shown in the paper using the described methods.
