摘要
使用RSM-SY5声波测试仪运用单孔一发双收的测试方法测量出十白(十堰至白河)高速公路黄龙隧道围岩的声波速度,进而分析了其围岩的松动情况和损伤情况,测试出松动圈范围大致在1.5m左右并且分布均匀,基于测试结果为合理安排工程爆破设计、隧道围岩安全防护以及预测动荷载作用下围岩长期稳定性提供了重要的依据。
In this paper, the RSM-SY5 acoustic tester by the way ofsingle hole a launch to measure income out ofshi bai （Shiyan to bai hei ） highway tunnel Hnanglong rock acoustic velocity and then analysis its surrounding rock loosening and damage situation, to test out loose circle more evenly distributed in the scope or about 1.5m. Based on the test results, providing an important basis reasonable arrangements for the blasting design, security and tunnel surrounding rock under dynamic load forecast long-term stability of surrounding rock.
