在隧道和矿山坑道、地下峒室等地下工程的开挖修建过程中,往往要对工程所处的岩体的物理力学特性进行必要的测试工作,以便对地下工程岩体稳定特性及力学指标作出正确评价。岩体的测试方法和手段很多。近年来,国内外正在运用和发展一种新的具有仪器轻便、测试周期短、精度可靠的岩体力学测试技术——声波探测法。
In the process of excavation and construction of tunnels, underground tunnels and underground tunnels, the physical and mechanical properties of the rock mass in the project are often tested in order to make the stability characteristics and mechanical indexes of underground rock masses Correct evaluation. Rock mass test methods and means of many. In recent years, at home and abroad, a new rock mechanics test technique - sound wave detection method with light weight, short test cycle and reliable accuracy is being applied and developed.
