摘要
基于围岩松动圈理论,采用超声波法对某地下水封油库洞室围岩进行松动圈测试分析。测试结果表明施工巷道围岩松动范围在0.5～1.3m之间,介绍了控制松动圈厚度的控制方法,可供洞室围岩支护设计参考。
The first large underground water-tight crude oil rock caverns is tested and analyzed by using the ultrasonic testing technique based on the loosen zone theory of the rock mass. The test results show that the thickness of the surrounding rock loosen zone at the gallery is between 0.5 meters and 1.3 meters. The test results provide the basis for the rock bolt design parameter. This paper also introduces methods of controlling the loosen zones and methods of rock cavern support.
