Title: Some Research Results from the Application of Geophysical Methods in Quickly Identifying Shallow Hazards in Dike and Dam Body Authors: Vũ, Đức Minh Đỗ, Anh Chung Keywords: Hollow cave;termite;sinkhole;Improved multi-electrode;Ground penetrating radar Issue Date: 2011 Publisher: VNU Citation: p. 57-66 URI: http://repository.vnu.edu.vn/handle/11126/4630 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-elect...
