摘要
在回顾国内外有关土工环剪仪研发及其应用研究工作的基础上,介绍了环剪试验设备的开发历程以及当今国际上对环剪试验系统研制方面的最新进展。总结了环剪仪在土工研究工作中的应用情况以及新的试验方法和测试技术等。着重阐述了利用环剪试验在对土峰后应变软化现象与残余强度分析、土的剪切带形成机制试验研究、地质灾害成因机制分析以及土工合成材料界面抗剪强度测定等方面研究中的主要内容、方法和成果。
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.
