ABSTRACT: Many geotechnical engineering problems involved a soiAstructure inter action. These problems are very complex because a sail-structure interaction. is a complex behavior of soils. Recently, solutions.afthe problems are based on:many conservative assumptions in order to simpl' the problems... To give a good solution needs soil parameters for modeling. A hyperbolic soil model is used in this research. This model is a simple model with all of soil parameters are determined from triaxial test results. The soil parameters are based on conventional, triaxial compression test results. In this research review was carried _out to determine the soil para meter and computer programs :to analyze both hyperbolic soil model para meters and back prediction. The soil is used in this research is a uniform sand with a relative density of 50%, 70% and undisturbed clay. Results of determination of soil parameters and the back prediction with computer programs showed a good agreement with laboratory test result.s. Hyperbolic soil parameters are Rfi Li, 0, c, K, .n, Kb, and m. Rased on the back prediction result, soil parameters are qualified for the input data in finite element, imulations as long as the strain in the soil. is relatively, small under. 5% and. the soil type included in loose sand or normally consolidated clay. This result of research could give contribution on soil modeling and to be input data in non linear finite element modeling as a solution for geotechniCal problems involved a soil-structure interaction for a design optimization.
