摘要
洞室声波测试是为获得准确、详细的岩体物理学参数,而在洞室内进行的一系列声波测试方法,通过计算和观察岩体声波速度的量值变化和分布规律,对岩体工程特性进行了评价,并了解洞壁岩体因施工开挖引起的松弛状况,还可以与岩体变形试验成果结合建立起动静态弹性模量之间的对比关系。
Adit acoustic wave testing is a method to do a series of acoustic wave testing in the adit which is used for obtaining accurate and detailed physics parameters of the rock mass.By calculating and observing value changes and distribution patterns of acoustic wave of rock mass,we can evaluate the engineering properties of the rock mass,understand the loose condition of the tunnel wall rock mass due to excavation,and combine test results of rock deformation to establish contrast relation between dynamic and static modulus of elasticity.
