Zusammenfassung:The invention discloses a rock compressive strength determination method, which comprises: sampling and processing a rock to obtain a standard cylinder sample; performing a non-destructive uniaxial compression acoustic emission test on the standard cylinder sample by using a uniaxial compression acoustic emission test device to obtain the rock elasticity modulus of the standard cylinder sample; monitoring acoustic emission test data in real time, and drawing a time-varying curve of acoustic emission accumulated energy; and obtaining the rock compressive strength according to the time-varying curve of the acoustic emission accumulated energy and the elastic modulus of the rock. According to the method, the experiment efficiency is improved, the sample loss is reduced, the compressive strength of the rock is determined by utilizing a curve of acoustic emission accumulated energy changing along with time, and a novel and efficient compressive strength determination method is provided. 本发明公开了一种岩石抗压强度的确定方法,包括如下步骤:
