NUMERICAL COMPARISON ON DEFORMATION CHARACTERISTICS OF THE SHORED MECHANICALLY STABILIZED EARTH WALL BETWEEN REDUCED-SCALE AND FULL-SCALE MODELS

摘要

A reduced-scale shored mechanically stabilized earth (SMSE) wall test was employed to validate a proposed numerical model through comparing the top surface settlement, reinforcement strain, and horizontal earth pressure. On this basis, according to the model ratio, a full-scale model is established for comparison with the reduced-scale model. It was found that the anchor connection with reinforcements can obviously strengthen the stability of the walls. Due to the different influencing factors in the reduced-scale and full-scale models, there are obvious differences in the regularities of distribution of horizontal displacement, vertical earth pressure, horizontal earth pressure, and reinforcement strain between the reduced-scale and full-scale models.
