地下水电站的厂房系统大多由纵横交错的复杂洞群组成，洞群施工过程中以及运行期围岩的稳定性是工程成败的关键。该文跟踪我国某地下水电站厂房洞群的施工过程，采用模式搜索优化技术和节理裂隙岩体模型非线性有限元方法，编制了Ｃ＋＋反馈分析控制程序ＮＡＰＡＲＭ９６，利用地下厂房监测系统提供的实测信息，对厂房洞群从时间和空间两个系列进行了仿真和位移反馈分析，得出了较为符合规律的结果。介绍了此项研究的阶段成果，并且对高地应力节理岩体中的地下洞群的施工稳定性问题提出了具有一定参考价值的建议。
The underground power station’s plant system mostly consists of criss-cross complex caves, and the stability of the surrounding rock during the construction of the creek and the operation period is the key to the success or failure of the project. In this paper, the construction process of a cavern cluster in a groundwater station in China is tracked. The C ++ feedback analysis control program NAPARM96 is developed by using the model search optimization technique and the nonlinear finite element method of the jointed fractured rock mass model. By using the measured information provided by the underground powerhouse monitoring system, The simulation and displacement feedback analysis of the two tunnels in time and space were carried out for the factory tunnel group. The results were in good agreement with the law. The stage results of this study are introduced, and some suggestions for the construction stability of underground caverns in the high ground stress rock mass are put forward.
