Analysis for Elastic Modulus of Main Fill Materials to Stress Properties of High Fill Embankment Structure

Abstract

The two sided mutual anchoring thin retaining wall is a new type of structure, the action mechanism is very complicated. It has aroused the widespread concern of the engineering community how to properly select the main filling materials of high embankment. The effect law of the index of elastic modulus on the stress of tensive bar and the lateral earth pressure are obtained based on the finite element analysis ANSYS software combining an engineering sample. Variation of elastic modulus index of main filling materials will have bigger influence on lateral earth pressure and the stress of tensive bar. These results in this paper indicate that enhances elastic modulus of main filling material can improve mechanical properties and provides the basis for the main filling materials of high filling embankment structure.
