Description

technical field

[0001] The invention relates to a water tank geophysical prospecting test device with variable spacing, and belongs to the technical field of geophysical prospecting. Background technique

[0002] There are two types of existing inter-hole geophysical testing methods. The first type is on-site geophysical testing, which is also the main type currently used. It is characterized by selecting a testing site and conducting geophysical testing on the testing site to form holes. The spacing and depth are generally several meters to tens of meters. Afterwards, according to the geophysical test requirements, acoustic tomography (CT) and penetration, seismic tomography (CT) and penetration, and electromagnetic tomography (CT) and transmission can be carried out between holes. The other is the indoor model test. According to the needs, a specific model is made in a certain proportion indoors and holes are formed. Acoustic tomography (CT) and penetrating geophysical te...
