声波测试技术,是向岩体(或岩石)发射一定频率的声波或超声波並研究其在岩体内传播规律的一种测试方法。根据声波在岩体中的传播特性,可以判断岩体的力学性质、确定岩体的强度和动弹性参数、探测硐室及采空区围岩的松动范围、了解岩体中结构面的分布情况及岩体的主应力方向等。声测技术用于探测岩体地质构造已有几十年的历史了。在我国,把声测技术应用于岩体力学也有十多年了。国内外的测试实践证明,由于这种方法具有简便、灵活、迅
Acoustic wave test technology is a test method that transmits sound waves or ultrasonic waves at a certain frequency to rock masses (or rocks) and studies their propagation rules in rock masses. According to the propagation characteristics of acoustic waves in rock masses, the mechanical properties of rock masses can be determined, the strength and dynamic elastic parameters of rock masses can be determined, the loosening range of surrounding rock in chambers and goafs can be detected, and the distribution of structural planes in rock mass can be known. And the main stress direction of the rock mass. Acoustic survey technology has been used to detect the geological structure of rock masses for decades. In China, it has been more than a decade since acoustic techniques were applied to rock mechanics. Tests at home and abroad have proven that this method is simple, flexible and fast.
