以云南省高黎贡山隧道为工程背景,应用声发射法对高黎贡山隧道中花岗闪长岩进行了原岩应力测试与分析研究。试验结果表明:本次声发射试验所测得的各应力值的大小与理论经验值误差不大,说明声发射技术能够较准确地对高地应力隧道中花岗闪长岩的原岩应力进行测量,能够在今后的工程实际中得到广泛的应用。 Taking the Gaoligongshan Tunnel in Yunnan Province as the engineering background, the original rock stress measurement and analysis of the granodiorite in the Gaoligongshan Tunnel was carried out by acoustic emission method. The experimental results show that the measured values ​​of the acoustic emission in this experiment have little error with the theoretical experience, which shows that the acoustic emission technique can accurately measure the original rock stress of the granodiorite in the high ground stress tunnel , Can be widely used in the future engineering practice.
