三维地质建模在公路工程中的应用

Application of 3D Geological Modeling in Highway Engineering

三维地质模型具可视化、二三维联动、量测等功能,可有效提高地质资料编辑及分析使用效率。某高速公路研究区发育暗河与拟建高速公路相交,对公路工程建设带来较大安全隐患,利用三维地质建模及工程测量技术,查清了暗河的形态、规模,并提出了处治措施,规避工程风险;同时,三维地质模型为后续力学分析提供了有效的地质模型。

The 3D geological model has such functions as visualization,two and three-dimensional linkage and measurement,etc.,which can effectively improve the efficiency of geological data editing and analysis.A underground river was developed in the research area of a highway and intersected with the highway to be built,which brought greater potential safety hazard for the construction of highway project.The 3D geological modeling and engineering measurement technology was used to make a thorough investigation of the form and scale of the river and treatment measures were proposed to avoid engineering risks.In the meantime,the 3D geological model provides an effective geological model for subsequent mechanical analysis.
