摘要

摘要: 在对承张高速某顺层页岩边坡资料收集和现场详细调查的基础上,通过赤平投影法对边坡稳定性进行了分析,确定了边坡的稳定性和边坡的滑移类型。结果表明：该边坡处于不稳定状态且滑移类型为滑移-拉裂型。计算了边坡极限失稳长度和后缘拉裂深度,并根据计算结果和实际情况设计确定采用微型桩对边坡进行加固,加固后边坡稳定系数计算结果满足设计安全要求。该分析方法和加固设计措施为以后该类型边坡的稳定性分析和加固设计提供借鉴。

Abstract: Based on detailed data collection and field survey of bedding shale slope in Chengde-Zhangjiakou expressway, the slip mode and slope stability are analyzed and determined by using the stereographic method. The results show that this slope is unstable, and the slip mode is sliding-tension type. The limit length of the slope instability is calculated. According to the calculated results and the local geological conditions, the micro-pile is recommended for the slope reinforcement. The stability results of the slope with micro-pile reinforcement meet the design requirements. The analytical method and design measures can be references for stability analysis of this type of slope and in the future.
