摘要
介绍了围岩声波的测试项目及其测试方法，阐述了量测数据处理的目的、内容和方法，并从最大位移值、位移率、位移时态曲线三个角度为依据进行施工管理；对二次衬砌稳定和衬砌效果的判别进行了论述，为设计和施工提供了较为准确的围岩分类。
The author introduces the item of acoustical test on wall rock and its testing method, illustrates the purpose, contents and method of measured data processing, carries through construction management from maximum displacement value, displacement rate and displacement ways curve, and discusses the stability and effect of secondary lining, which to offer more accurate classification of wall rock for design and construction.
