作为电子计算机时代产物之一的有限元法,已成功的应用于固体力学、流体力学、电磁学等领域中。在水工、建筑、铁道、交通、采矿等部门可以用来处理非均质、非线性的应力—应变性态以及复杂边界条件的工程技术问题,定量地求解应力和位移等。这就给设计和施工提供一个数量上的概念,结合其它方面积累的经验,可应用它来指导生产实践。无论是露天或地下开采总是分阶段或分中段开采的。一个大断面的巷道或 Finite element method, one of the products of computer era, has been successfully used in fields such as solid mechanics, fluid mechanics and electromagnetism. In hydraulics, construction, railway, transportation, mining and other departments can be used to deal with heterogeneous, nonlinear stress-strain behavior and complex boundary conditions of engineering and technical problems, quantitative solution of stress and displacement. This provides a quantitative concept of design and construction that can be applied to guide production practices, combined with experience gained in other areas. Whether open-pit or underground mining is always carried out in stages or in mid-section. A large section of the roadway or
