| 摘 要： | 通过对潜山面和内幕EDA介质地面地震记录数值模拟及其波场特征分析,在了解地震波场的动力学特征对裂缝介质的敏感性基础上,确定主要以振幅,其次是频率的地震波动力学特征为裂缝检测被检参数,以均方振幅与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.

| Abstract: | The sensitivity of dynamical characteristics of seismic wave in EDA medium is understood through seismic numerical simulating and wave-field characteristics analysis of the buried hill surface and its internal phase. Therefore the dynamical characteristics are acted as detected parameters for fracture detection (primary amplitude, secondary frequency). And the amplitude of mean square and central frequency are acted as evaluation parameters. The base of the fracture detection theory is built up based on these studies. |
