用浅层地震反射法探测河北山前平原活断层依据及效果

重大工程建设选址,必须了解厂区及周围地质断层的活动性,它是评价工程抗震能力的重要依据之一。根据地震反射层与地质层位关系,我们曾在北京市、定州市及邯郸市等地,为国家重点建设工程选址,用浅层地震反射法探测活断层,均取得较好的地质效果,为评价工程抗震性能提供了可信的资料。

THE APPLICATION OF SHALLOW SEISMIC REFLECTIONMETHOD TO THE INVESTIGATION OF ACTIVE FAULTSIN PIEDMONT PLAIN OF HEBEI PROVINCE:ITS BASISAND EFFECTS

In choosing the site for an important construction project, we must knowthe activity of faults within or surrounding the factory area, which seems tobe one of the major bases for evaluating antiseismic capacity of the constru-ction project.Based on the relationship between the seismic reflection layer and thestratigraphic horizon, the author used the shallow seismic reflection methodto investigate active faults during the siting of important construction projectsin such cities as Beijing, Dingzhou and Handan. The results obtained haveyielded fairly good geological effects and thus provide reliable data for evalu-ating antiseismic capacity of the construction project.
