摘要
选用水泥石膏相似材料制作模型,工艺简单、材料来源广、价格低廉,其材料与岩石的结构及破坏方式均类似,是一种较好的相似材料。本文着重研究了骨料含量、水泥含量、石膏含量和用水量对水泥石膏模拟材料强度及弹性模量的影响,得到了其相应的变化曲线及变化规律,并研究证明了用该相似材料来模拟岩石性能的可行性,提出了用该相似材料模拟部分沉积岩的配合比,为进一步研究分形节理岩体的力学性能打下了坚实的基础。
The effects of aggregate content, cement content, gypsum content and the consumption of water on the strength and elastic modulus of the similar material of cement-gypsum were mainly researched. Its corresponding change rule and curve were attained; the feasibility which simulates the rock performance by the similar material was proved by research. The ratio of some sedimentary rock simulated by the similar material was put forward. The results build a firm foundation for the further research mechanical property of rock masses which have fractal joints is established.
