目前人工地震广泛应用于油气勘探、活断层探测以及其他一些工程作业等领域,人工地震在应用中也会像天然地震一样,对地面产生振动,从而造成不同程度的影响。然而,对于由人工地震激发的“震级”和“烈度”研究目前在国内开展得较少,尤其是在四川地区更是一片空白。本文以川西地区不同地震地质条件下,通过人工爆破激发地面震动,对人工地震产生的震级、烈度进行记录,然后经过理论分析和实际计算得出震级烈度的大小,并与《中国地震烈度表》对比,从而评价人工地震是否对建筑物、工程设施产生破坏提供有力依据。通过研究发现,在安全距离内,人工地震不会对建筑物和工程设施产生危害性的影响。
At present, artificial earthquakes are widely used in the fields of oil and gas exploration, active fault exploration and other engineering operations. Artificial earthquakes also vibrate on the ground like natural earthquakes in application, resulting in varying degrees of impact. However, studies on “Magnitude ” and “Intensity ” triggered by artificial earthquakes are currently carried out less in China, especially in Sichuan. In this paper, we record the magnitude and intensity of earthquakes produced by artificial earthquakes by stimulating ground vibrations under different seismic geological conditions in western Sichuan. Then, the magnitude of earthquake magnitude is obtained through theoretical analysis and practical calculation, and compared with “China Earthquake Intensity Table” Contrast, in order to assess whether artificial earthquake damage to buildings, engineering facilities provide a strong basis. The study found that within a safe distance, artificial earthquakes will not have a harmful impact on buildings and engineering facilities.
