| 摘 要： | 为了研究傍山隧道爆破振动在邻近边坡的传播规律,设计了4个隧道模型进行爆破试验,试验结果表明:傍山隧道爆破振动在邻近边坡上的传播随水平距离及爆心距的增大而减小,随高差增大而增大,受爆心距的影响最大,垂向振速径向切向。边坡形态、最终边坡角和台阶坡面角都会对爆破振动在边坡传播产生影响,4个模型坡顶与台阶边坡坡面都出现了振速放大现象,傍山隧道爆破振动对顶部的影响比对坡面的影响大,对台阶边坡的影响比直面边坡的影响大。

| Abstract: | In order to research on the propagation of blasting vibration on adjacent tunnel adjacent to mountain slope, designed 4 tunnel model test, test results show that the paraxial propagation of blasting vibration on the slope of the mountain tunnel in the vicinity decreases with the horizontal distance and increase the distance from the explosion, and increases with the increasing height, distance from the maximum effect by explosion the Vertical vibration velocity > Radial > tangential. The shape of the slope, the ultimate slope angle and bench slope angle of blasting vibration influence on slope propagation, 4 model slopes and step slope appeared that near the elevation amplification effect, blasting vibration effect on the top of the mountain tunnel effect on slope, influence step slope ratio The influence of the side slope is great. |
