本文通过清江隔河岩导流隧洞施工中的围岩稳定声学监测,对围岩性态及喷锚支护效果进行了分析,对塌方预报给予了说明。实践表明:声学方法是一种行之有效的岩体原位监测手段。
In this paper, through the acoustic monitoring of surrounding rock stability during the construction of Geheyan diversion tunnel in Qingjiang River, the character of surrounding rock and the effect of shotcrete and bolt supporting are analyzed and the landslide prediction is given. Practice shows that: Acoustic method is an effective means of rock in situ monitoring.
