摘要
由于数据结构的差异,用于岩土工程三维可视化的网格与用于数值模拟的计算网格之间存在本质差异,如何通过两种网格的共享实现三维地质模型与数值模拟之间的集成是岩土工程建模的重要内容。在对层状岩体三维可视化网格与数值模拟网格的特点进行剖析的基础上,提出了基于松散模式的三维规则格网与FLAC3D基本元素之间的转化方法,从理论上实现了“可视”与“可算”的结合。将其应用于我国某海底隧道的选线研究中,证明了该方法的合理性和有效性。
The difference between the two grids for three-dimensional visualization and the element for numerical simulation in geotechnics is obvious due to the variety of data structure. Consequently, it is of much importance to study the integration of three-dimensional visualization modeling and mechanical analysis. After dissecting mesh properties of the three-dimensional visualization and the numerical simulation, a method of loose mode which converts three-dimensional grid to FLAC3D model is brought forward. Its application to a submarine tunnel proves that it is reasonable and effective.
