【摘要】 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。更多还原

【Abstract】 Artificial earthquake is widely used in oil and gas exploration,active fault detecting and engineering application. However,in practical application an artificial earthquake generates different vibrates on the ground like natural earthquakes according to the different geological condition. We collect different recordings under several different geological conditions. The recorded data include magnitudes,intensities generated by artificial earthquakes in the western regions. Then through the theoretical calculations and analyses,we gained magnitudes and intensities calculated and then compared with that from Chinese seismic intensity table. The vibrations would be evaluated whether the artificial earthquake can damage buildings,engineering facilities. Through our study,the artificial earthquake will not cause buildings and facilities collapse if these constructions are beyond a safety distance.更多还原
