| 中文摘要: |
| 滑坡体三维信息是进行滑坡危险性分析不可缺少的工程地质因子,三维滑坡体模型可以更加真实地反映边坡的实际形态,因此越来越多的实际工程要求采用三维理论方法进行稳定性分析。文章介绍了一种基于空间三维极限平衡法的滑坡灾害体危险性评价方法,即利用常规地形数据快速获取滑坡体的极限安全系数来分析灾害体发生失稳的概率,并通过空间信息技术实现灾害体影响区域的三维可视化,可为滑坡灾害的危险性分析提供有效、可靠的决策支持。 |
| 英文摘要: |
| The three dimensional information of the landslide is an essential factor to analyze the risk of the landslide. It is more effective to describe the real shape of the landslide by using the three dimensional models, so more practical engineering requires the utilization of three dimensional theoretical method to analyze the stability of landslide. Based on the space-based 3D limit equilibrium method this paper introduces a method, to analyze the safety of landslide. The method is used to general terrain data to get the safety of landslide fastly and analyze the instability. At the same time,it models the real three dimensional model of the influenced area and actualizes three dimensional visualization, which supports the risk analysis efficiently and reliably. |
