本文叙述在高围压下用各种靜力学方法及动力学方法测定岩石試件的弹性参量。曾对在地壳中分布甚广的岩石:輝綠岩、玄武岩、花崗岩及石灰岩进行了測定。結果表明,在压力为1—1000公斤/厘米~2范围內,上述岩石的弹性参量均随压力的升高而不断增加。从弹性力学的概念出发,闡明了靜力弹性参量及动力弹性参量的差別,对比了各种不同方法測定的結果,以及它們随压力变化的情况。指出在实践中分別采用靜力弹性参量及动力弹性参量的合理性。
This paper describes the determination of the elastic parameters of rock specimens by various statics and dynamics methods under high confining pressure. The widely distributed rocks in the earth’s crust have been determined: diabase, basalt, granite and limestone. The results show that the elastic parameters of these rocks increase with the increase of pressure under the pressure of 1-1000 kg / cm ~ 2. Based on the concept of elasticity, the differences of static elastic parameters and dynamic elastic parameters are clarified, and the results of different methods are compared with their changes with pressure. The rationality of using static elastic parameters and dynamic elastic parameters separately in practice is pointed out.
