Description
Technical field
The present invention relates to technical field of civil engineering, especially a kind of pin-connected panel stiffness variable mould for shaketalle test
Molding box.
Background technology
In hypogee（Such as subway, tunnel）Structured testing in, shaketalle test has consequence.In underground
In the shaketalle test of structure, generally structural model is placed in model casing together with ground body Model, to simulate actual field
The seismic response of structure in ground.Therefore model casing structural form, particularly its lateral rigidity characteristic whether with simulated place
Dynamic characteristics be adapted, have considerable influence to the reasonability of result of the test.
Currently used test model box for vibrating table includes rigid box and the major class of laminar shear case two.In the design of model casing
In index, the lateral rigidity of model casing actually reflects the outer place of research range to Rock And Soil in research range（And structure）'s
Effect of contraction, therefore its lateral rigidity should be adapted with the dynamic characteristics of actual place.To hard rock place, should use does not allow side
To the rigid mould molding box of detrusion；To weak soil place, the laminar shear model casing for allowing lateral shear to deform should be used.
Rigid box is generally directly welded by steel member, also needs to set up diagonal brace sometimes to increase its rigidity.Laminar shear
The species of case is more：It is stacked stacked with annular frame to be divided into rectangular frame by plane geometric shape；By vertical applied force feature
It is divided into bearing plate formula and top plate suspension type；It is divided into unidirectional shearing and double direction shear formula by deformation direction is allowed；Slided by interlayer
Shifting feature is divided into ball spout formula and Universal wheel type.
But for pan soil or soft rock place, the sidewise restraint of Rock And Soil is acted between hard rock and weak soil, therefore is simulated
The model casing lateral rigidity in the type place also should be between rigidity and flexibility.If still adopt rigid box or laminar shear
Case, there will be considerable influence to the reasonability of result of the test.
