Using geophysical land radar to solve accidents

According to Professor and Doctor of Science Ngo Van Bai, former head of the Department of Geophysics, Department of Petroleum, University of Mining and Geology, it is necessary to test the geophysical method of soil to contribute to solving the "pit problem". death."

Deathhole appeared in Hanoi.

The surrounding " death hole " environment is complicated by many underground cables, underground sewers and other disordered materials under the asphalt road surface. But those who cause such difficulties can also distinguish according to their own characteristics.

First need to test the available land radar and the accompanying specialized software to verify the effectiveness and advantages and disadvantages in some typical locations such as "death hole," where there are alarm signs. (subsidence, cracks, leaking water, .) as well as where traffic activities are subjected to large loads with high frequency without any signs of danger, but need to ensure there is no "death hole" on the side. below.

Thereby it will be seen what kind of soil radioactivity contributes to solving the "death pit" types, more complex types must combine soil radar with other methods.

Geophysical science, an industry that investigates the underground structure by physical methods without destroying the earth, has been in place for a long time, from searching very deep oil and gas traps in the continental shelf of South Vietnam. until detecting small, shallow termites in dike body in the North.
