Comparative analysis of concrete integral overpass with variable soil characteristic

Abstract

In this paper concrete integral overpass with span of 30 meters on magistral road which based on piles is considered. It is analysed influence of soil stiffness on value of design forces and pile stress. Three types of soil is considered in this analysis, where stiffness of soil was determined with characteristic of soil layers. For this analysis was made numerical model of this overpass in software CSiBridge v20 where is soil modeled with "springs" (flexible supports) placed along the piles whose stiffness match with stiffness of soil layer.
