| 摘 要： | 给出工程地质数据库的结构,并利用标准地层层序表和钻孔数据,根据层面TIN模型,建立了工程地质三维模型;在此基础上提出一种实用的工程地质三维剖切的实施方法,该方法通过剖切平面与层面TIN边的交点生成虚拟钻孔,把虚拟钻孔所在的地质剖面作为约束条件,将虚拟钻孔和实测钻孔一起重新构建层面TIN模型,并实现工程地质三维剖切。该方法简易可行,对层状地质结构的三维剖切效果较好,能满足工程地质分析和地质解释等应用的实际需要。

| Abstract: | 3D geological cutting can completely and unambiguously define the geological structures for the site being modeled,including complex boundaries and embedded seams,which can help geologists and engineers to understand their research objects better and greatly enhance the accuracy of geologic analysis.On the basis of the research of before,the structure of engineering geological database is put forward with application of standard stratum sequence table and drilling hole datum,and based on layer surface TIN(T... |
