Some Research Results from the Application of Geophysical Methods in Quickly Identifying Shallow Hazards in Dike and Dam Body
Small and shallow caves are frequently found on the dike and dam system inside our country, leading to some risks of subsidence, seepage, even dyke and dam rupture. The handling of this problem is relatively simple if we can accurately identify the location of these hollow caves. The question is...

| Summary: | Small and shallow caves are frequently found on the dike and dam system inside our
country, leading to some risks of subsidence, seepage, even dyke and dam rupture. The handling of
this problem is relatively simple if we can accurately identify the location of these hollow caves.
The question is how to study and find out the geophysical method to quickly and accurately
determine the location and size of these caves for timely treatment in order to improve the
efficiency of the survey. This paper presents some new results obtained when studying and
applying the Improved multi-electrode (2D and 3D) and Ground penetrating radar methods to
rapidly determine the hollow caves at K112+697 position of the Red River right dam in Hà Nội
and at K21+900 position of Dao River left dam in Nam Định. The paper also assesses the
capability and effectiveness of each method in the determination of this object. |
