Abstract

 Dynamic earth pressure, due to its complicated nature and the unknown problems associated with the values and point of application of the pressure developed behind the wall, needs to be further studied and investigated. In spite of large and extensive research carried out in this regard, a specific method or building code, by which dynamic earth pressure can be calculated accurately, have not been recommended. One of the most reliable ways to determine dynamic earth pressure may still be to develop a physical model, which, in some cases, is time and money consuming.Although many investigations have been performed to study the behavior of retaining walls subjected to earthquake loadings and valuable results have been achieved in this regard, the exact pattern of the pressure acting behind the wall and the soil-wall interaction in this condition have not been clearly specified.To study the behavior of retaining walls under cyclic surcharges, as a limited but the most common type of the dynamic loadings produced by the traffic loadings, due to easier nature, may play a fundamental and helpful role in this respect.In this paper, a great effort has been made to model soil-wall interaction under cyclic loading surcharges by a special geotechnical software (PLAXIS) using the finite element method. Since, prior to this study, a physical model, capable of studying earth pressure behind the medium scale model retaining walls under different loading and constraint conditions, has been developed in the department, the experimental data obtained from this model during different tests, have been used to verify and validate the analytical model developed in this study.The influences of frequency, number of load cycles, surcharge amplitude, distance of load from the wall and the soil density have been studied and investigated. Finally, the analytical results were compared with the experimental results and some new and further recommendations have been suggested in connection with soil-wall interaction under cyclic surcharges.
