本文对由水泥、尾砂和粒径大至15mm的碎石形成的胶结碎石充填体的力学特性,胶结充填矿柱中的应力分布及其强度设计进行了研究。 1.胶结碎石充填体的应力应变关系 对胶结碎石充填体的力学属性进行了分析讨论,结果表明,胶结碎石充填体与岩土、混凝土和胶结尾砂充填体这些材料的力学性质有许多相似之处,是一种具有明显非线弹性,各向异性和非均质性的材料,可用岩土力学的研究方法来研究。
In this paper, the mechanical properties of cemented gravel packs formed from cement, tailings, and gravel with particle sizes up to 15 mm, stress distribution in cemented filled ore columns and strength design were studied. 1. The stress-strain relationship of cemented gravel packs analyzed and discussed the mechanical properties of cemented gravel packs. The results showed that the mechanical properties of cemented gravel packs and rock and soil, concrete and rubber end sand packs were Many of the similarities are a kind of material with obvious nonlinear elasticity, anisotropy and heterogeneity, which can be studied by the research method of rock and soil mechanics.
