摘要
通过巴东地区某滑坡滑带土的天然含水率与密度试验、土粒比重试验、颗粒分析试验、界限含水率试验、击实试验以及不同剪切速率的滑带土重塑样的三轴固结不排水剪试验,探讨不同剪切速率条件下滑带土抗剪强度参数的变化趋势,分析滑带土试样的应力-应变关系,揭示滑带土的物理力学特征及其对滑坡的影响,以期对该类型滑坡的防治提供有价值的基础性建议。
Based on the natural moisture content and density test, specific gravity test, grain size analysis tests, water content limits test, compaction test and tri-axial consolidated undrained shear test of remodeling sample of sliding soil under different shear rates for the sliding zone soil of a landslide in Badong area, we explore the change trend of shear strength parameters of the sliding zone soil under different shear rates, analyze the stress- strain relations of the sliding zone soil samples, reveal the physical and mechanical characteristics of sliding soil and its effects on the landslide, hoping to offer valuable basic recommendations for the prevention and cure of this type of landslides.
