基于GIS技术的运动学岩坡滑动可能性分析

摘要

Using the theory of kinematic to analyse the geometric relationship between the geologic structure and Slope of Rock to identify Slope of Rock Sliding Possibility.Combining the Kinematic and GIS technic to create a representative model of the geologic structure and the terrain across the study area and applying the GIS＇S spatial analysis functiong to supply an accuracy obvious and efficiency of results. By applying a GIS-based kinematic model to analyse slope of rock sliding possibility around the dam of DA-GANG mountain hydroelectric station demonstrated the feasibility and usefulness of performing kinematic analysis within the GIS environment and also the superiority comparing with the traditional kinematic analysis.%利用运动学原理来分析岩体结构面与岩坡的几何关系，可以识别岩坡滑动破坏的可能性。将运动学与GIS技术相结合构建有代表性的研究区域地质结构面与地形模型，并通过GIS的空间分析功能，提供更加准确、直观、高效的分析结果。最后，运用GIS技术的运动学模型对大岗山水电站坝区岩坡的滑动可能性进行分析，论证了GIS环境下运动学分析的可行性和有效性，以及相对于传统运动学分析的优越性。
