FLAC在隧道开挖建造过程数值仿真模拟

摘要

Combined with a practical engineering project, the article applies the FLAC-3D software which is about Fast Lagrangian Analysis of Continua to build up a model of a tunnel. The model applies the Mohr-Coulomb Elastic-Plastic Model to have a numerical simulation study about the construction of the tunnel, by means of which we can get some results of stresses and displacements. Based on the results, we can have a good simulation process and give some reference and bases, which made the practical projects more safe, economical and reasonable.%　　本文结合具体的一项工程，运用三维快速拉格朗日差分分析计算软件FLAC-3D建立一个隧道的计算模型，采用Mohr-Coulomb Elastic-Plastic Model，对隧道的开挖建造过程进行数值仿真模拟计算研究，从而可以得到隧道建造开挖不同过程的应力、变形位移等规律，以此给予一个较好的模拟过程，通过研究结果为隧道设计以及之后的施工给予一定的参考意义和依据，使得工程建设更加安全、经济、合理。
