矢量图解法在边坡稳定性评价中的应用

Application of Vectorgraph in Appraisal of Slope Stability

控制岩质边坡稳定性的主要因素,是岩体的结构面。岩质边坡的稳定性评价,通常是通过分析结构面与坡面的关系进行的。在极坐标上坡面和结构面都可用矢量表示,结构面矢量与坡面矢量之间夾角和模的大小能准确反映两者之间的关系。本文从这一点出发提出了一种评价边坡稳定性的新方法。

The chief factor to dominate the stability of rock slope is structural planes in the rock . Generally, the evalution of stability of the rock slope is analyzed by the relationship between the structural planes in the rock and the plane of slope . Both plane of the slope and the structural plane in the rock may be showed by vector with polar coordinates .The relationship between the structural plane and the plane of the slope can be reflected exactly with their vector. A new method for evaluation of the stability of the slope based on is pricpiple was discussed in the paper.
