An economical and reasonable arrangement scheme for the piles and GR was obtained. This method can effectively exploit the membrane effect and improve the utilization efficiency of the bearing capacity of the soil between piles. The results show that the method is reasonable and applicable. Finally, the method is applied to field tests for comparison. Therefore, the project cost can be reduced. By controlling the settlement of soil between piles, the bearing capacity of soil between piles and the membrane effect of embankment can be fully utilized. Based on the obtained model, a method for optimizing the soil bearing capacity of GRPSEs is proposed. The model considers the relationship between the geosynthetic reinforcement (GR) and the pile spacing. Therefore, in order to solve the problem of insufficient bearing capacity of soil between piles, we established a settlement calculation model of soil between piles based on membrane effect. As a result, the utilization efficiency of the bearing capacity of the soil between the piles is low and the project cost is high. These factors cause the membrane effect to not be exploited. During the construction process, the pile spacing is reduced to meet the requirements for the embankment bearing capacity and settlement. The reason is that they are designed for bearing control as defined in the past. However, the application of the GRPSE system is often restricted by its high-cost. The geosynthetic-reinforced pile-supported embankment (GRPSE) system has been widely used in road construction on soft soil.
