摘要
西南山区地质条件复杂,具有地形起伏多变、地层岩性多样、构造作用强烈等特点.为进一步提高路径区域工程地质条件分析评价的精度,本文以云南境内的某500kV超高压输电线路工程为例,通过MapGIS平台来量化设计路径区域内的地形地貌条件、地质构造、地灾、岩性、人类活动等影响因子,采用信息量法建立了数学模型,确定分级标准,绘制工程地质分区图,为路径的选线、优化提供了量化依据.
Abstract
The geological conditions of the southwest mountainous area are complex,with varied topography,diverse stratigraphic lithology and strong tectonic action.In order to further improve the accuracy of analysis and evaluation of engineering geological conditions in potential route,taking a 500kV ultra-high voltage transmission line project in Yunnan Province as an example,and uses MAPGIS platform to quantify the influencing factors,including topographic and geomorphic conditions,geological structure,disaster,lithology,and human activities.The mathematical model is established by information method,the classification standard is determined,and the engineering geological zoning map is drawn,which provides quantitative basis for route selection and optimization.
