| 摘 要： | 滑带土的强度特性对于边坡稳定具有重要的控制作用，揭示滑带土强度指标的变化规律是进行边坡安全性评估的基本前提。针对一库岸古滑坡滑动带中的含粗粒细粒土，进行了滑带土强度特性的试验研究：通过现场大剪试验和室内固结快剪试验分析了滑带土的剪切性状，确定了再生强度、现场折减强度和固结快剪强度；根据现行反复剪切试验在确定含粗粒细粒土残余强度时的不足，对试验方法和试验仪器进行了改进，提出了滑带土的残余强度指标，并与其他剪切条件下的强度指标进行了比较；基于试验结果的统计分析，探讨了土体含水率、塑性指数及粗粒含量对剪切强度指标的影响，并总结了含粗粒细粒土与一般黏性土或砂土在剪切性状方面的诸多不同

| Abstract: | Strength property of slip zone soils has important control action for slope stability.It is essential premise that revealing the variation law of strength indices for slope stability analysis.Aiming at an ancient landslide in reservoir area,the experimental study of shear strength of fine-grained soil containing coarse-grains in sliding zone was carried out.Based on large-scale field shear test and laboratory consolidated quick shear test,the shear characters of slip zone soils were compared;and the strengt... |
