本文对长江武汉段天然石英砂进行了不同终止压力下的侧限实验,指出了该砂样的压缩特性,研究了其在高应力下的破碎机理。对所用试样在试验前后进行了颗分试验,研究了破碎率与压力及砂样粒径的之间关系。
In this paper, the lateral confinement experiments of natural quartz sand in the Wuhan section of the Yangtze River under different stopping pressures were conducted. The compression characteristics of the sand samples were pointed out and their crushing mechanism under high stress was studied. The test samples before and after the particle test carried out to study the relationship between the crushing rate and pressure and sand particle size.
