摘要
对优势结构面理论及其重要性进行阐述,并将其用于某一高陡岩质边坡的稳定分析工作中。在充分分析相关工程地质资料的基础上,确定在评测指标上占据优势的结构面。利用赤平投影图分析各组优势结构面对边坡稳定性的影响程度,得到边坡剖面相应的控稳优势面组合,并将该组合考虑到岩体稳定性计算分析模型中。利用极限平衡分析软件slide综合评价该边坡在优势结构面影响下的稳定性,并以优势结构面为关键因素,提出相应的治理措施建议。
Preferred plane theory and its importance is briefly introduced here, and it is applied to the stability analysis of a high and steep rocky slope. Based on the related geological data,the planes which hold advantage in each evaluation metric are determined. By analyzing the influence degree of the preferred planes to slope stability with the stereographic projection, stability-controlling preferred plane combination is obtained and is taken into account in the calculation-analysis model of rock mass stability. Using the slide software as an analysis tool,a comprehensive stability evaluation of the slope is obtained,together with the treatment advices which the preferred planes are fully considered.
