| Abstract: | Based on the review of development and application of geotechnical ring shear apparatus at home and abroad, the course of ring shear apparatus design and its utilization are introduced. By summarizing the latest technical advances of ring shear test, the testing methods and technology, and the results of employing ring shear apparatus in the research fields are elaborated, such as the analysis of soil post-peak strain softening and residual strength measuring, the experimental study of the mechanism of shear band formation, the explanation of geological hazard mechanism, the assessment of interface shear strength properties of geosynthetics, and so on. |
| Keywords: | ring shear apparatus strain softening residual strength landslide shear band geosynthetics |
