三维地下空间数字建模中,地层建模通过三角网等方法已经能够方便地实现,地下建(构)筑物的快速建模目前仍然是一个难题,尤其是对体形复杂的地下结构,如地铁枢纽车站。通过将基于特征的建模方法应用于一个复杂地铁枢纽车站建模实例,证明基于特征的建模方法能够有效解决复杂地下建(构)筑物数字建模的困难。
In 3D digital modeling of subsurface space, stratum modeling can be conveniently realized by methods such as triangulation. The rapid modeling of underground structures is still a difficult problem, especially for complex underground structures such as the subway Terminal station. By applying the feature-based modeling method to a complex metro station modeling example, it is proved that the feature-based modeling method can effectively solve the problem of digital modeling of complex underground structures.
