生产实践表明,矿柱设计的形状、大小,对其受力破坏有着密切的关系。这一问题已引起国内外学者专家的广泛兴趣和注意,并已开始对其进行研究。 本文试图用试件加载试验找出不同尺寸的试件受力的破坏情况,为矿柱设计和现场岩体试验提供依据及参考。 The production practice shows that the shape and size of the pillar design are closely related to its damage. This issue has attracted widespread interest and attention from scholars at home and abroad, and has started to study it. This article attempts to use the specimen loading test to find out the damage conditions of different size specimens, and provide basis and reference for the pillar design and on-site rock mass test.
