摘要
分析了潜山面 EDA介质地面地震数值模拟及其波场特征 ,认为地震波的动力学特征比运动学特征对裂缝更敏感 ,而且振幅比频率好 ,因此选择动力学特征来检测裂缝比用运动学特征检测裂缝好 .确立了以振幅和频率的地震波动力学特征作为检测裂缝的参数 ,以均方根振幅和中心频率作为检验检测结果正确与否的评价参数 .为建立裂缝检测方法奠定了理论基础 .
The seismic digital simulation and the wave field of EDA medium of the buried hill surface were analyzed. The result shows that the dynamical characteristic of seismic wave and the amplitude are more sensitive to fracture than kinetic characteristic and frequency. So the dynamical characteristic is better than kinetic characteristic in detecting fracture. Therefore the dynamical characteristic ( amplitude and frequency)can be used as a detected parameter for fracture detection; And the amplitude of mean square root and central frequency can be used as evaluation parameters, which has laid a theoretical foundation fracture detection.
