摘要: 钻孔是获取地层信息最直观、准确和详细的手段,地层的内部构造可以通过钻孔信息应用三维建模方法表达出来。为了保证隧道施工安全,实现盾构隧道顶部地表层的可视化,提出了一种基于钻孔数据构建三维地层模型的方法:首先应用ArcEngine对钻孔数据进行预处理,得到钻孔的空间信息; 基于三维约束Delaunay四面体化算法和预处理后的离散钻孔信息构建TEN(四面体格网)模型; 在ArcEngine的平台调用数据库中的钻孔数据、地表层属性等信息,实现地表与钻孔信息的三维显示、信息查询和地层分析等功能。

Abstract: The most intuitive and accurate and detailed method for obtaining the information of stratum is through boreholes, so the formation of internal structure of stratum can be expressed by 3D model based on the data of boreholes. In order to ensure the safety of the tunnel construction and realize the visualization of stratum surface which at the top of the shield tunnel giving a method of constructing 3D stratum model based on the data of boreholes. At first, ArcEngine applied to preprocessing the data of boreholes and gain the spatial information of boreholes; and then constructing TEN model based on the algorithm of three dimensional constraint tetrahedron of Delaunay and the information of discrete boreholes which have been preprocessed. By calling the data information of boreholes and the properties of stratum surface and so on from the database through the platform of ArcEngine, realized the function of 3D display of the information of stratum surface and boreholes, information query, analysis of stratum and so on.
