中文摘要：

爆破振动波在岩土介质中的传播规律主要受岩体介质特性以及装药参数的影响，但在地形起伏较大的情况下，地形地貌对爆破振动波传播具有非常大的影响。结合广东岭澳核电站二期工程爆破负开挖振动监测，分析凹、凸形地貌对爆破振动波的传播影响。分析结果表明：凹形地貌对爆破振动波具有衰减效应，其衰减系数不仅与其宽度和深度有关，还与最大段药量和爆源距有关；凸形地貌不仅对爆破振动波具有放大效应，而且放大效应具有方向性，振动速度垂直向较水平向放大效应明显；凸形地貌对振动波的放大系数随相对高程增大而增大，而随爆源比例距离增大而减小。另外，凸形地貌的放大效应还与岩性、岩石构造和节理发育程度有关。

英文摘要：

The law of propagation of vibration wave of blasting is mostly affected by property of rock material and parameters of explosive loadings, whereas the topography affects greatly propagation of vibration wave under condition of a variety of terrains. Many explosion tests are carried out in the second period engineering project in Ling＇at Nuclear Power Station, Guangdong Province. The dissemination of vibration wave of blasting is analyzed in concave or protruding topography. The results show that the concave landforms have great effects on decreasing scale of vibration wave of blasting. It is found that the attenuation coefficient of vibration wave in concave landform is relative to its width and depth and to charge weight per delay interval and explosive distance. The protruding topography can enhance scale of vibration wave of blasting The amplification effect is related to orientation in protruding topography, and that the vertical vibration velocity is amplified more than that of the horizontal vibration. The amplified coefficient of vibration wave blasting is augmented with relative altitude, but decreases with the scale distance of explosive in protruding topography. In addition, the scale effect of protruding landform is also related to property of rock mass, and the structure of rock and the growth of cranny.
