摘要
以城市区域地质、钻孔、剖面等数据为基础,结合3DGIS方法技术、3D可视化技术以及一系列有关城市地质特征的描述、模型、分析评价的方法,利用三维建模理论构建研究区3D地质体模块,并在3D可视化下综合解析城市的砂土液化,将城市地质工作和城市规划结合,构建一个城市三维地质信息系统,提高城市地质工作的研究水平。以通州地区为例,结合砂土液化灾害理论知识从三维角度进行地质稳定性评价,划定通州区地下潜在砂土液化灾害区域,为后续灾害防治工作提供决策依据。
Based on the data of regional geology, drilling and profile, combined with 3D GIS technology, 3D visualization technology and a series of description, model and analysis evaluation method of urban geological characteristics,the 3D geological model was established by 3D modeling theory, and in the 3D visualization of the comprehensive analysis of the city of sand liquefaction, the combination of urban geological work and ur6an planning,to create an urban 3D geological information system,improve the level of urban geological work. Taking Tongzhou area as an example, combined with the theory of sandy soil liquefaction disaster,the geological stability evaluation is carried out from three aspects, and the potential sand liquefaction disaster area in Tongzhou District area is delineated, which provides a decision-making basis for the prevention and control of disaster.
