Investigation of the Stability of Geosynthetic Reinforced Soil Retaining Structures
This paper utilizes numerical method to simulate the application of geosynthetic reinforced soil retaining structures. The SLOPE/W computer program was employed in this study to introduce the calculation of the reinforcement forces and the strengthening mechanical behavior of the soil structure as well as the failure mode. When using the SLOPE/W program for analyzing geosynthetic reinforced soil retaining structure, each layer of the reinforcement was considered with the identical tensile force on the sliding surface on the same slice. Once the reinforcements committed pull-out failure, they bore different tensile forces. Although the reinforcement committed break-off failure, the reinforcement tensile forces were the same. The unique component is the neat consideration for making the different required length of reinforcement. Under the circumstance of the failure surface not cutting through the reinforcement, it did not provide any resistance force. In addition, SLOPE/W was used for the slope stability analysis of the geosynthetic reinforced soil retaining structure built in FoGuang University, Ilan County, Taiwan. Slope condition in the absence of the reinforcement gave the factor of safety as 0.93, which did not meet the requirement of slope stability at all. With the support of reinforcements, the safety factor was increased to 2.19, which matches the specification under normal conditions.
