岩石地下工程要作到安全经济,在很大程度上取决于岩石洞的稳定性评价。在地下工程稳定性分析中,有限元法已经成为一种十分重要的方法。但是,要期望得到符合实际的结果,为设计和施工提供可靠的依据,还必须解决许多有关的基本问题,例如,岩体力学模型的选择,初始应力场的大小及分布规律,洞体稳定性的判别准则,考虑时间因素的影响等
The safety and economics of rock underground projects depend to a large extent on the evaluation of the stability of rock caves. In the analysis of underground engineering stability, finite element method has become a very important method. However, in order to obtain realistic results and provide reliable basis for design and construction, many basic issues must be solved, such as the selection of rock mechanics model, the size and distribution of initial stress field, and the stability of the cavern. Discriminant criteria, considering the influence of time factors, etc.
