采矿工程中存在很多的随机性因素,这些随机因素关系到矿柱的可靠度.依靠传统的安全系数法不能考虑矿柱载荷和物理力学特性的随机性,因而具有很大的误差和局限性.本文介绍的随机有限元法将随机理论与有限元相结合,充分考虑了矿柱载荷的随机性和弹性模量的随机性,使矿柱可靠度的计算更符合实际.

In mining engineering, there are lots of random factors, which are relative with the reliability of the orebody. In traditional methods of the reliability, because of not considering the random of the elastic model and the force, there are often a lot of error and limitation in result. This paper introduces the SFEM, at the same time, considering the random of the elastic model and force, the re...
