| 摘 要： | 探讨了利用GOCAD建立工程建筑三维地质模型的关键技术问题,提出了以克里金插值和离散光滑插值相结合来建立地层界面以及采用GOCAD中的GR ID功能代替SOLID功能建立三维地层实体的方法。以北京市某经济开发区建筑场地为例,利用GOCAD建立了该场地第四系沉积层的模型。实例分析表明,由此建立的三维地质模型能更好地反映实际情况。

| Abstract: | The traditional geological information can not meet the requirement of the current engineering construction.3D geological model is developed.Technical issues are discussed about the 3D modeling of engineering construction formation using GOCAD.Two methods are put forward.One is combining Kriging interpolation with discrete smooth interpolation to produce strata interface,the other is using GRID function instead of SOLID function in GOCAD.A model of the Quaternary of a construction site in Beijing by the GOCAD software produced by the two methods proves to be effective. |
