Experimentally comparison of shaking table and pseudo-static parameters of polymeric-strip reinforced-soil walls

抄録

The conventional design procedures for seismic stability evaluation of the reinforced soil retaining walls are based on the pseudo-static approaches. The accuracy of the pseudo-static analyses relies on adopting an appropriate seismic acceleration coefficient (Kh). Most of the proposed methods for calculating Kh are based on theoretical assumptions and the validation of this vital parameter has not been evaluated based on an experimental approach. In this study, a new method is introduced to estimate Kh for reinforced-soil walls adjacent to the rock slopes using the results of shaking table and push-back pressure tests. The results presented herein consider the acceptable seismic performance of the retaining wall and are compared with the other proposed coefficients in the literature. The proposed method of this study can be developed for all types of retaining systems.
