Abstract

To study the stress and deformation characteristics of geocell-reinforced earth retaining wall under static and dynamic loads, this paper designed large model tests of reinforced earth retaining walls under static and dynamic loads, and analyzed the distribution laws of parameters such as vertical earth pressure, vertical sedimentation, horizontal displacement of face plates, and dynamic acceleration of reinforced earth retaining walls. The experimental results show that the increasing number of reinforcement layers enhances the lateral confinement effect of geocells, making the internal stress of the retaining wall more sufficient and balanced. The ultimate bearing capacity is increased by 120%, and the maximum horizontal displacement of the wall surface is reduced by 14.3%. The ultimate bearing capacity of the retaining wall model under dynamic loads is 70% of the ultimate bearing capacity of the static load model, and the horizontal displacement of the wall surface at the model failure time is twice that of the static load model in the same conditions. Compared with the amplitude of dynamic loads, the dynamic load frequency has a weak effect on the vertical earth pressure of retaining walls. Therefore, it is recommended that frequency should not be considered as a key influencing factor during calculating and analyzing the earth pressure of reinforced earth retaining walls under dynamic loads.
