Technical field
The utility model relates to the underwater shaketalle test technical fields of building, water conservancy etc., are a kind of achievable underwater vibrations
Dynamic platform terrain simulation and partitioned organization.
Background technique
Complicate soil medium and hydrodynamic environment can significantly affect the response pattern and destructive process of structure in earthquake engineering,
Therefore how it is authentic and valid simulation earthquake-hydrodynamic force coupling excitation be earthquake engineering analog study premise.Currently, shake table is made
Fast-developing for the most effective simulator of earthquake engineering, loading capacity constantly increases, and array quantity is increasing, shake table
Itself gradually from water-less environment to water environment change, and water environment functions of the equipments also enrich constantly with it is perfect.
But, problems are still had with regard to the construction situation of underwater shake table (array) and for the use of function at present.
Firstly, water-bed (seabed) landform is sufficiently complex in true environment, causes flow fields environment complicated, act on the hydrodynamic force item in structure
Part is complicated, and the simple uniform flow field or the simulation of wave field of carrying out can not really show the hydrodynamic characterisitic in environment, therefore build
If the false bottom of analog landform is very necessary.The false bottom in water conservancy, harbour and coastal engineering model test is mostly used at present
The traditional building materials such as stone-laying, mortar, needing to expend the more time is built, and construction cost is higher, disassembly process compared with
It is long, it is non-recyclable and reusable.For the coupling test of hydrodynamic force and earthquake, the manufacture of test specimens such as soil, structure on shake table with
Installation needs to expend more cost and time, if false base ring border still uses conventional method, the test period then can greatly be elongated, vibration
The utilization efficiency of dynamic platform can decrease.Secondly, certainly existing the feelings that each shake table is tested respectively for the underwater shake table array
Condition, then region has water and alternation of wetting and drying problem at the ultimate challenge of underwater shake table array utilization rate.Currently, both at home and abroad
The shake table array to come into operation is water-less environment, and underwater shake table is only separate unit, does not there is using first for the underwater array
Example, therefore do not have relevant test method or device for realizing the partition experiment of the underwater shake table array, also there is not correlation
