GEOTECHNICAL CHARACTERISTICS OF THE TERRAIN AND CALCULATION OF BEARING CAPACITY FOR BRIDGE No. 3 OF MOTORWAY TARCIN – KONJIC

In paper is given overview on geotechnical characteristics of the terrain on location of a bridge number 3, on highway Tarcin – Konjic. Complexity of geological structure, in near surface where it consists from sediments of weathering crust to depth of around 30,0 m, as well as in substrate that consists of sediments of clayey debris, determined the way of foundation. On software package Geo 5 is done a semi-analytical approach for determining the load capacity of the pile and extent of subsidence in relation to given load. Pile is modeled with beam elements where is observed behavior of surrounding terrain according to Winkler-Pasternak modele, and shearing force to the contact of pile and soil are determined based on Mohr-Coulombo criteria. Changeable characteristics on the terrain demanded analysis of every pile for which are given propositions for foundation and allowed load.
