摘要
由于GIS强大的功能从一般的数据存储到复杂的空间分析及图形显示,在岩土工程分析中亦必将成为一个常用工具。本文研究基于GIS栅格数据和4个边坡稳定三维极限平衡模型,开发了一个GIS扩展模块用于边坡三维安全系数计算。考题和实例计算表明了该模块的正确性和便利性。
GIS （geographical information system）, with its capacities range from conventional data storage to complex spatial analysis and graphical presentation, is becoming a powerful tool for geotechnical engineers. In this study, combining the GIS grid-based data with four proposed column-based 3D slope stability analysis models, a GIS extension, 3DSlopeGIS, has been developed to implement the algorithm in which all the input data are in the same form of GIS dataset. Some widely addressed examples have been evaluated and an actual 3D slope problem has been analyzed. The results show the correction and usability of this GIS-based tool for assessing the 3D stability of a slope.
