Discussion on Time-Lapse Geophysical Monitoring Hidden Troubles Defects in Dikes

针对堤防隐患探测的复杂性,本文对堤防隐患的时间推移地球物理监测进行了探讨.首先讨论了堤防隐患探测的特点,然后以时移地震为例,描述了时移地震的正演思想、反演模型及非重复性时移地震数据匹配处理的基本思路,最后提出了堤防隐患的时间推移地球物理监测的基本思路及要研究的关键内容.开展堤防隐患的时间推移地球物理监测的系统研究,地球物理探测必能在堤防隐患探查中发挥重要的作用.

Considering the complexity of detecting of hidden troubles defects in dikes,the time-lapse geophysical monitoring technique of the dike engineering exploration is discussed.We firstly discuss the characteristics of the probing hidden defects detection,dangers in dikes;then,by the example of time-lapse seism,describe the forward idea of time-lapse seism and inversion model;by the example of time-lapse seism,we also give the basic idea of data matching processing in non-repeated time-lapse seism.Finally,the basic main idea and key point of time-lapse shift geophysical monitoring in detecting hidden defects troubles in dikes is proposed.By starting the research of the time-lapse shift geophysical monitoring system of perils in dikes,the geophysical monitoring must play a more and more important role in dike defects detection engineering exploration.
