Intend research, wherein geologic body can not be with changing, it is impossible to quickly changes geological form according to site environment.Due to simulating the list of geology
One property, causes model assay systems to reuse, greatly wastes resource.It is badly in need of proposing that one kind can carry out a variety of works
Condition is simulated, and can change geological form, the model assay systems that can be reused according to geological environment.
3. wave impact analysis is lacked.Existing pilot system is more to be tested on stable water body, and its water surface is stable, but
In real site environment, wave has certain influence on seimic wave propagation.When there is wave, sea level is free to rise and fall
Surface, reflection of the seismic wave at the interface is complex, simultaneously because marine arrange focus and observation side using towing cable mode more
Formula, when wave is larger, can convert the depth of towing cable in the seawater, influence the seismic data of collection.
4. observation system arrangement is limited.Limited by model assay systems, seismic survey system observed pattern is generally fixed peace
Dress, it is impossible to realize the Rapid Combination of different observed patterns as requested, greatly reduce the research of different observed patterns, therefore urgently
The automation control system of observation system Rapid Combination can be realized by treating that proposition is a kind of, improve physical experiments efficiency.
