| 摘 要： | 采用MTS-815程控伺服刚性试验机,对天然石英砂进行不同围压条件下的固结试验,研究其颗粒破碎特性,探讨围压对石英砂颗粒破碎的影响。结果表明,40兆帕以下,固结压力与颗粒破碎程度的变化关系不稳定,当破碎达到一定程度后,颗粒级配趋于良好,围压对其影响逐渐减弱。

| Abstract: | The consolidation tests on natural quartz sand under different confining pressures are conducted through using MTS-815 rock mechanical test system.The grain crushing characteristics of the quartz sand are studied and the impact of different confining pressures on quartz sand grain crushing is explored.The results show that,at a pressure of less than 40 MPa,the relationship between consolidation pressures and the changes in grain crushing is unstable.When the grain crushing reaches a certain level,the grain distribution turns good and confining pressures gradually weakens their impact. |
