چکیده مقاله
In railway and road construction, the retaining walls are widely used and calculation of soil pressure on it has been one of the important issues in the engineering and academic community The present laboratory study is intended to investigate the conditions of rupture in retaining walls with a narrow backfill between them The theories of Rankin 1857 and Coulomb 1776 have been widely used in the field of calculating lateral soil pressure Also, Mononobe Okabe 1924 tried to simplify seismic dynamics into horizontal and vertical forces This simplification has turned complex dynamic problems into static problems However, the aforementioned theories have assumptions that provide limitations for specific types of retaining walls, such as 'narrow backfill', in which the extension of the failure surface from the foot of the wall to the upper surface of the soil behind the wall is not possible, and these basic assumptions are no longer valid As a result, the old assumptions are no longer valid, and therefore results with those assumptions will lead to adverse effects on design and economic issues Unequal settlement at the top of backfill and increasing pressure on the walls during cyclic motion are the important results of this study
