【摘要】 利用基于GIS(Geographic Information System,地理信息系统)栅格数据的三维极限平衡分析模型,可以充分考虑边坡的三维复杂空间特性。经过数据的获得、数据的处理、模型的建立和稳定性分析,不但给出了边坡的三维安全系数,而且给出了危险滑动面上的滑动力分布矢量图。结果表明,滑动面上力的分布极不均匀,呈现明显的复杂空间特性。更多还原

【Abstract】 Based on the grid data of the geographic information systems (GIS), the complex 3D spatial properties of slope can be fully considered in 3D limit equilibrium analysis. Through data acquisition, data processing, model establishing and stability analysis, the 3D safety factor can be calculated; and also the vector diagram of distribution of sliding forces on critical slip surface can be mapped. The result indicates that the distribution of forces on the slip surface is extremely uneven and shows obviously complex spatial properties.更多还原
