- 摘要:
- 在岩质边坡中，岩体的失稳与破坏主要受岩体内结构面的控制，它们相互之间的空间分布位置、组合关系(包括自然边坡或边坡开挖面的产状)和结构面的物理力学性质等，对边坡的稳定都起着至关重要的作用.将野外测量的结构面资料，用一定的几何图形植入三维地形模型中，可以直观显示各软弱结构面的空间展布规律和交切关系，再根据赤平投影原理进行分析统计，确定优势产状，进而对边坡在潜在不稳定块体宽度、高度、体积、失稳模式和滑动方向做出定量的判断，从而指导现场工作人员采取处理措施.
- Abstract:
- In the rock slope,rock’s stability and failure is mainly controlled by the structure of rock.Space distribution between them,combinational relation(including natural slope and slope excavating surface’s situation),structural surface’s physical and mechanic quality and some other things play important parts in the rocks’ stability.So the law of space distribution and mutual relation of the feeble structure can be shown directly according to the planting into the three-dimensional model of the structural materials surveyed in the field by the means of plank plate;and then make sure the advantages according to the analysis and statistics to projection principle.In this way a quantity’s judgment can be made quickly and simply to the safety coefficient of slops,mass width,mass height,mass bulk,mass unstable model and mass slipping directions so that workers on the spot can take relative actions.
