Abstract :
Main idea of present research is evaluation of statically behavior of soil-steel structures under military vehicles loading. For this purpose, a soil-steel structure with horseshoe shape profile with maximum span equal to 9.88 meters considered. According to Code No.139 Tank weight affected on numerical model. Plates dimensions based on CHBDC code were selected. In present study, analyses in three position were performed. These positions are based on variations of earth fill, types of soil-steel structure plates and location of loading. Numerical analysis was carried out by Plaxis program in 2D condition and according to finite element method. Results of this study showed that, in soil with suitable geotechnical properties (i.e. increasing elastic modulus and internal friction angle), stability of soil-steel structure go up and settlement values decreases. Also, types of plate in soil-steel structure can be effective in behavior. So that, plates with high thickness and more flexibility is useful for application in soil-steel structure.
