摘要
本文讨论了土壤类型、土层厚度、土质强度等因子对坡体崩塌的影响， 初步分析了土质强度参数随颗粒级配、含水量、密度、粘土含量的变化趋势。通过临界坡度试验， 给出了判别土坡稳定性安全系数： Ｆ＝ Ｋｆ （１－ ω／ωＬ） （ｔｇφ／ｔｇβ＋ ｃ／ｒｓＨ）。
The paper studies the effects of such factors as soil types, layer thickness and soil strength etc to slope avalanche, preliminarily analyses the variation trend of soil intensity parameters following grain composition, water capacity, soil density and clay content Based on critical slope experiments, a formula about safety coefficient for distinguishing slope stability is given: F=K f (1-ω/ω L)(tgφ/tgβ+ c/ γ sH)
