The underground space detected, but due to being influenced by the pipe network of surface buildings and underground bulky complex, survey line is sometimes difficult
With arrangement, Effect on Detecting is also undesirable.Numerical simulation is a kind of to take out numerical model from practical study object and studied
Method, it is time saving and energy saving, but numerical simulation is a kind of naive model abstracted, can only obtain universal law, and underground is empty
Between again be extremely complex, so the result of numerical computations often differs greatly with actual conditions.Model test refers in reality
The method studied actual condition with the model of different scale under the conditions of room is tested, can reappear prototype using model test
Various phenomenons and process, artificially control variable and experimental condition, can not only obtain preferable test effect, but also reduce and grind
Study carefully the period.
Physical prospecting simulation test device currently used for the complicated underground space situation of simulation is not yet developed, and more existing
Analogue experiment installation is the ground electricity situation of the resistivity such as simple analog or single ground electricity unfavorable geologic body, this with practically
Lower complex situations are not inconsistent；And device arrangement form is relatively simple, is only capable of realizing the arrangement of single geophysical exploration device, nothing
Method is detected and is compared using other physical prospecting means, and the repeatability of experiment is poor.Therefore, it develops one and can be used for geophysics
The physical analog test apparatus of exploration, to geophysical exploration technology improve and assure the safety for life and property of the people have reuse make
With with great social value and scientific value.
