| 摘 要： | 岩体声学特性与岩体结构、破碎程度、风化程度密切相关。为了获得岗上隧道工程岩体声学特性,采用声波测试技术对某隧道工程岩体及岩芯进行测试与分析。研究结果表明波速与岩体的风化及破碎程度密切相关。掌握工程岩体的声学特性,对岩体结构分类、岩体动弹性参数测试、以及岩体质量评价等具有重要意义,可为隧道工程的设计与施工提供重要依据。

| Abstract: | The acoustic characteristics of a rock mass has a close relationship with the structure,joint development degree and the weathering degree of the rock mass.The acoustic wave velocity is measured by using the acoustic wave testing technique on the rock mass and core of a tunnel project for gaining the acoustic characteristics of Gangshang tunnel’s rock mass.It is of great significance to study the acoustic characteristics of a rock mass for classifying the structure,testing the elastic parameter,and evaluating the quality of the rock mass,therefore it could provide important bases for the design and construction of tunnel engineerings. |
