摘要
工程高边坡在开挖过程中由于卸荷变形等因素,整体稳定性受长大裂隙控制。通过对长大裂隙的调查描述,建立二维及三维地质模型,在定性评价的基础上进行定量计算,并进行分析,对边坡的稳定性进行评价和预测,研究结果对类似高边坡稳定性研究具有借鉴意义。
The overall stability of a project high slope is controlled by large long fissures due to unloading deformation during excavation.Through investigation of the large long fissures and establishment of 2D and 3D geological models,and making quantitative calculation and analysis,the slope stability is evaluated and forecast.The results can be referred to for stability study of similar high slopes.
