摘要
为探究滑坡对广州增城至从化高速公路K8+160~K8+515段的稳定性影响,以该边坡的变形特征和监测结果为依据判定出该边坡的滑动面,再通过极限平衡法和数值模拟法计算断面的稳定性系数,分析该边坡的稳定性。分析结果表明:该区域有存在浅层滑坡和深层滑动的可能性,饱水状态下,由于边坡稳定性降低,导致边坡极易发生整体滑移。该分析结果可用于广州增城至从化高速公路的防护依据。
In order to explore the influence of landslides on the stability of the K8+160~K8+515 section of the Zengcheng-Conghua expressway in Guangzhou,the sliding surface of the slope was determined based on the deformation characteristics of the slope and the monitoring results.And then the limit equilibrium method and the numerical simulation method was used to calculate the stability coefficient of the section and the stability of the slope.The results show that there is the possibility of shallow landslides and deep sliding in this area.In the saturated state,due to the decrease of slope stability,the slope is prone to overall slippage.The results can be used as a basis for protection of the Zengcheng-Conghua expressway in Guangzhou.
