综合物探方法探测城市隐伏活动断层的研究
|
摘要
随着我国城镇化建设的步伐加快,在开展小区规划的工作中,查明第四纪隐伏活动断层对于抗震评价与设计显得十分重要,已成为地球物理工作者多年来研究的热点问题。本文在阐明隐伏活动断层及其地球物理特征的基础上,针对城市特殊的场地条件和干扰环境,提出了以浅层地震反射波法为主,高密度电阻率或探地雷达、氡气测量等方法为辅的新型综合物探组合模式,并深入研究了其可行性和互补作用。实践表明,上述综合物探方法组合可适应于第四纪不同埋深、不同尺度、不同类型的隐伏活动断层探测,且是行之有效的方法。
With the rapid development of the urban construction in our country,it is important to detect the the quaternary buried active faults for the seismic evaluation and design in the work of developing the community plan,which has became a hot topic in field of the geophysics in recent years.On the basis of elucidating the geophysical characteristic of the buried active faults and with the special site condition and interference environment of the city,this paper puts forward a new comprehensive geophysical exploration combination model with the shallow seismic reflection wave method and the other methods such as the high density resistivity method or ground penetrating radar and radon measurement.And this paper further studies its feasibility and complementation.The study shows that combination of the comprehensive geophysical exploration method can be adapted to the detection buried active faults of the Quaternary's different buried depth,different sides and different types.
