| 摘 要： | 为了评价日本千叶县某住宅区周边大范围边坡的滑坡危险度,探讨了一种基于GIS的三维边坡稳定性评价方法。首先根据已有的CAD格式的地形等高线图及有限的钻孔数据,得到地表、地层、地下水的三维GIS数据。在依据边坡倾角、倾向等地形特性对该大范围边坡划分边坡单元的基础上,采用一种基于GIS栅格数据的边坡稳定三维极限平衡分析模型计算了研究区域各边坡单元的安全系数,进行了滑坡危险性分区评价。本研究对于如何利用有限的现场调查数据来进行高精度的数值计算分析,以及GIS在地质防灾领域的更深层次的应用具有一定的参考价值。 |

| Abstract: | For evaluating the landslide hazard adjacent to a residence area in Tiba Province of Japan,a GIS(Geographical Information System) based three-dimensional(3D) slope stability analysis approach is proposed.The GIS data of ground surface,strata,and groundwater,which are spatially distributed,are obtained from the limited investigation data such as CAD-format contour map and the boring data.Based on the inclination angle and the dip direction of slopes,the study area is firstly divided into slope units,and then a grid-based 3D deterministic slope stability model is adopted to calculate the safety factors of each slope unit,to identify the location of potential failure surfaces.This approach shows the capability of using the limited investigation data to implement highly precise analysis of the slope stability for a wide area. |
