| 摘 要： | 文章以真实地质钻孔、隧道横断面及线位设计文件为基础,引入虚拟钻孔,将地质剖面图与加密的地层建模边界作为地层建模约束条件,用三棱柱体建立地层三维模型,提高了地层建模精度；采用先规则建模后正则集合运算的方法生成复杂隧道实体,实现了隧道穿越地层的开挖、剖切等.该数字化建模方法在厦门翔安海底隧道工程应用中取得了较好的效果.

| Abstract: | Based on actual geological drilling data,tunnel section and line design documents,a three-dimensional model was established using triangular prism and encrypted stratum modeling(under restrained conditions) in order to allow virtual drilling,which improves the accuracy of stratum modeling.Using regular operations and following modeling rules,representing excavation and sectioning of the stratum being crossed by the tunnel,a complex tunnel was produced.This numerical modeling was successfully applied to the ... |
