综合地球物理方法在城市活断层探测中的应用综述——以哈尔滨城市活断层探测项目为例
|
摘要
综述从活动断裂的研究和进展出发,通过追溯国内外活动断裂研究发展历史,结合当前城市活动断裂研究的理论与方法,认为地球物理的综合物探手段在城市活断层探测工作中将会越来越重要。文中重点介绍了城市活断层探测工作中所采用的地球物理方法的类型,以及在区域探查与初步鉴定阶段、详细探测与精确定位阶段、孕震构造探测阶段可能涉及到的各种地球物理探测方法、适用范围及所能解决的主要问题等。文章结合哈尔滨城市活断层探测项目实例,表明在面对岩石和地层的众多物性差异和勘查结果的多解性时,地球物理的综合物探方法在提高资料的反演和解译准确度方面具有十分重要的意义。
From the research and progress of active faults,and through retrospection of research and development activities fracture history in home and abroad,the current international research methods and trends on active faults,the review proposed that the geophysical method is one of the most important methods.The paper elaborated on various kinds of possible geophysical methods for seismic active fault exploration and their main features.The paper also discussed the scopes of related geophysical methods application and the major problems that they can solve in the different periods of active fault exploration,such as regional survey or preliminary investigation,detailed exploration or precise location,and the identification of seismogenic structures.At the same time,the discussion proved that the geophysical methods have great significance in urban active fault detection through the example of active fault detection in Harbin city,especially,in the improvement of accuracy of interpretation and results.
