地下厂房开挖过程中围岩状态的可视化仿真研究

将地下厂房围岩稳定有限元计算的结果，通过计算机程序数据采集，实现地下厂房岩石开挖过程围岩力学状态的可视化仿真。以地下厂房为例，实现随开挖过程厂房围岩位移、应力、屈服范围、锚杆应力等状态的动态可视化仿真，这对保证地下厂房开挖的稳定起到了重要的作用。在施工系统仿真中融入围岩稳定性分析将是可视化仿真发展的必然趋势。

Study on visual simulation of the state of surrounding rock in the excavation of underground powerhouse

The data of the state of surrounding rock during the excavation of underground powerhouse is analyzed with finite element analysis program. According to the collected data by computer,the visual simulation of the surrounding rock stress status is realized during the excavation. As an example,this paper demonstrates dynamical visual simulation of some state changing,such as displacement, stresses, yield range, anchor stresses of the surrounding rock. Such simulation plays a very important role in ensuring the stability of underground powerhouse during its excavation.
