摘要
贯入试验已经在岩土工程中得到了广泛的应用,颗粒材料中的贯入过程也可以作为一种煤炭开采方法来进行研究。文章利用离散元数值工具,模拟了颗粒材料中的贯入试验,并从主应力场、速度场、转角场等微观角度对贯入机理进行了探讨。
Penetration test has been used widely in geotechnical engineering; and penetrating m granular materials can be treated as a new method for coal mining. By performing a series of penetration test in granular materials with Discrete Element Method, this paper has discussed the penetration mechanism from the point of main stress field, velocity field and particle rotation field.
