基于遥感和GIS的工程岩土体信息提取方法研究:以东北界河地区为例

Research on engineering rock and soil information extraction method based on remote sensing and GIS

工程岩土体中岩体类型、土体类型及厚度是影响工程稳定性的重要因素之一。本文基于遥感和GIS技术对东北界河地区工程岩土体信息提取方法进行了研究,提出了一套对工程岩土体信息快速提取及转化的方法。该方法不仅可以查清不良的地质现象,而且能在较短时间内掌握该地区的工程地质概况,为调查工作程度较低,交通条件差的边远地区提供了快速掌握其工程地质概况的有效的方法,近一步拓展了遥感地质工作的服务领域和方向。

Rock mass type,soil type and thickness in engineering rock and soil are one of the important factors affecting the stability of the project.Based on remote sensing and GIS technology,this paper studies the method of information extraction of engineering rock and soil from the boundary river area in northeast China,and proposes a method for rapidly extraction and transformation of engineering rock and soil information.This method can not only find out the bad geological phenomena,but also grasp the engineering geological background of the area in a short period of time,and provide an effective way to quickly master the engineering geological profile for the remote areas with low investigation work and poor traffic conditions.The method further expands the service field and direction of remote sensing geological work.
