本文把较大地震前观测到的地震波振幅异常变化与模拟实验的结果及理论分析加以对比,借助于地壳介质的变化对振幅比前兆异常特征提出了某些物理解释。较大地震前观测到的地震波振幅比时间变化呈“低值——上升到稳定高值——发震——回到正常值”的形态;主震危险区位于异常区内,多数在比值梯度大的地方,临震时比值骤增,各台比值峰值出现时间由震中距,方位角不同而有序。岩石压力实验中压力达岩石破坏强度50—60%以后,P波振幅随压力增加而下降,幅度较大;A_S/A_P随加压而下降,达破坏强度90%以后,迅速回升;若加载达破坏强度之95%时充水稳压,P波振幅在各方向均减小。在理论上把孕震过程中介质的变化分别用单相和多相介质模拟,多相介质中考虑以气和水为孔隙流体,给出本构关系,求出速度和垂直向位移。理论工作表明:A_S/A_P在孔隙介质为气时比为水时小;P波振幅变化大;孔隙度大,振幅比变小。介质中应力集中程度达岩石破坏强度60%前后,可分别用单相和多相来描述介质。两相中,微裂隙张开,以气体为主,A_S/A_P变小,呈负异常,达90%时,A_S/A_P上升,围压大于孔隙压,孔隙流体以水为主,且水进速率大于孔隙度增大速率;临震时予...

本文把较大地震前观测到的地震波振幅异常变化与模拟实验的结果及理论分析加以对比,借助于地壳介质的变化对振幅比前兆异常特征提出了某些物理解释。较大地震前观测到的地震波振幅比时间变化呈“低值——上升到稳定高值——发震——回到正常值”的形态;主震危险区位于异常区内,多数在比值梯度大的地方,临震时比值骤增,各台比值峰值出现时间由震中距,方位角不同而有序。岩石压力实验中压力达岩石破坏强度50—60%以后,P波振幅随压力增加而下降,幅度较大;A_S/A_P随加压而下降,达破坏强度90%以后,迅速回升;若加载达破坏强度之95%时充水稳压,P波振幅在各方向均减小。在理论上把孕震过程中介质的变化分别用单相和多相介质模拟,多相介质中考虑以气和水为孔隙流体,给出本构关系,求出速度和垂直向位移。理论工作表明:A_S/A_P在孔隙介质为气时比为水时小;P波振幅变化大;孔隙度大,振幅比变小。介质中应力集中程度达岩石破坏强度60%前后,可分别用单相和多相来描述介质。两相中,微裂隙张开,以气体为主,A_S/A_P变小,呈负异常,达90%时,A_S/A_P上升,围压大于孔隙压,孔隙流体以水为主,且水进速率大于孔隙度增大速率;临震时予滑,应力部分解除,孔隙部分闭合,孔隙饱和,振幅比出现峰值,至于空间分布则要考虑应力积累与调整部位介质强度不同,可能造成孔隙度及饱和度不同所致。由于本文的物理解释中综合了实际观测,模拟实验和理论分析的结果,又把应力状态与介质变化联系起来,故此种解释可能具有成因观点。

The paper deals mainly with the major results of the experimental studies of hydrogeo -chemical effects by hydrofracturing organized for the first time in China. This is a com- prehensive observational experiment of many diciplines with more observational items on a large scale. In this experiment some advanced test instruments and technologies are used; the method of observation under repeated application of pressure for three times has been adopted; the results are repeatable and reliable; and valuable experimental data have been collected. The most noticeably affected items observed in this experiment are radon, water level and the compositions of other gases. At the same time, the experiment has verified that the mechanisms causing water level changes are not only the transmission of stress-strain in rock, but there is an even more important possibility, hydraulic conduc- tion of pore pressure increase in the water-bearing system. The experiment also shows that the hydrofracturing method is of great importance for testing the mechanical effects of various precursory phenomena, for probing precursory anomalous mechanism and for guiding seismicity monitoring and earthquake prediction.

本文着重介绍了我国首次组织的水压致裂水文地球化学效应实验研究的主要成果。这次实验规模大、观测项目多,是一次多学科的综合观测实验。在实验中使用了一批先进的测试仪器和技术,采用了三次加压重复观测的方法,取得了重现性好的结果和可靠的实验资料。这次实验产生“效应”最显著的项目是氡、水位及其他气体组分,同时验证了引起水位效应的机制不仅是岩石压力应变的传递,而更重要的可能是含水系统孔降压力升高的水力传导。实验表明,水压致裂方法对于检验各种前兆现象的力学效应,探索前兆异常机理及指导监测预报有重要意义。
