摘　　要：为研究岩石波速与强度参数的变化关系,通过对阳煤矿区几种常见岩石进行波速测试、抗压试验、抗剪试验、抗拉试验,分析了岩石波速与强度参数的变化特征和规律。结果表明:岩石的抗压强度、抗拉强度、黏聚力与波速均存在显著的正相关性。不同种类岩石的变化规律具有相似性,又具有各自的特点,彼此的变化范围有一定的交集,但又有明显的层次性。3种粒径砂岩的波速与抗拉强度、抗压强度均呈现出较强的线性变化规律,通过线性拟合可以较为准确地表达出砂岩的抗压强度、抗拉强度与波速的变化关系。不同岩石的黏聚力与波速的变化有一定的差异,但整体呈现出正相关变化趋势,并且有较强的幂函数变化关系。In order to study the variation relationship between rock wave velocity and strength parameters, the variation characteristics and laws of rock wave velocity and strength parameters were analyzed through wave velocity tests, compression tests, shear tests and tensile tests on several common rocks in Yangmei mining area. The results showed that the compressive strength, tensile strength, and cohesion of rock all have significant positive correlations with wave velocity. The variation laws of different kinds of rocks were similar, but had their own characteristics. The variation range of each other had a certain intersection, but had an obvious hierarchy. The wave velocity under three kinds of particle sizes all show a strong linear variation law with tensile strength and compressive strength of sandstones. The variation relationships between compressive strength, tensile strength with wave velocity of sandstones can be expressed more accurately through linear fitting. The variation of cohesion with wave velocity of different rocks is different to some extent, however, shows a positive correlation trend as a whole, and has a strong power function relationship.
