A STUDY OF REINFORCED SOIL STRUCTURES UNDER SEISMIC EXCITATION

ABSTRACT

Reinforced soil structures are widely used in many urban and rural areas around the world, of which many are located in geographical regions with medium to high seismic activity. Most of these structures are parts of the lifeline network of the respective area. Therefore it is important to understand and if possible predict the behavior of these structures under an expected seismic activity. In this study an attempt is made to recall the rather old Finite Element program SSCOMP and to enhance the ability to use this program for the analysis of reinforced soil structures under given base excitations. The efforts consisted of regeneration of SSCOMP from printed material as an operational program, testing and verification of the regenerated program with respect to reports of earlier studies with the program, development and implementation of the pseudo-dynamic approach and the required script as the supplement processor, performing a number of numerical analyses and comparing the results with a case history of a centrifuge test and with the results of a commercial finite difference program FLAC. As a final step, an extended parametric sensitivity analysis for static and dynamic loading conditions is conducted. It is shown that SSCOMP, together with the implemented pseudo-dynamic approach, yields acceptable results to provide an insight on the expected behavior of the reinforced soil structures, given that the FE model, the relevant parameters and the obtained results are carefully selected, used and evaluated, respectively.
