摘要
考虑季节性冻融循环作用的影响,并结合边坡冻融滑塌的现场观测数据,对边坡进行浅层稳定性分析。边坡稳定性安全系数主要与以下因素有关:坡面荷载、坡度、融化深度以及融化土体的抗剪强度。对季冻区高等级公路边坡防护设计提出了合理化的建议。
Considering the effect of seasonal freeze-thaw circulation,superficial layer stability analysis is conducted to the slope combining with the onsite observation data of slope freeze-thaw collapse.Safety factor of slope stability is mainly related to following factors： load on the slope,inclination,thawing depth and shear strength of thawing soil body.Rational proposals to slope protective design of highways in seasonal frozen region are proposed.
