Setting a panel outside the soilbags-constructed retaining wall may affect the behavior of the wall. Therefore, a full-scale test of the soilbags-constructed retaining wall with fixed panels and with unfixed panels were conducted to explore the influence of the panel on the deformation mode and lateral earth pressure of the wall. The results show the walls with fixed and unfixed panels deformed laterally in a cantilever-like manner, but the lateral earth pressure acting in the fixed-panel wall is greater than that in the unfixed-panel wall. A calculation formula for calculating the earth pressure acting on the soilbags-constructed retaining wall under limited displacement was established based on the linear elastic constitution theory, and then it was used to analyze the relationship between the lateral earth pressures and lateral strain. It is found that distribution of the lateral earth pressure of the soilbags-constructed retaining wall with unfixed panel is close to the calculated active earth pressure as a result of the poor deformation constraint of the unfixed-panel, which indicates that the flexible characteristics of the soilbags-constructed retaining wall can be fully utilized by the wall with unfixed panel, so as to effectively reduce the earth pressure behind the wall.
