Bridge pier contact, upper support seat 4 is contacted with bridge, and vulcanie item 6 is provided between lower support base 1 and upper support seat 4, hard
Flexible deformation can occur in a certain range for rubber strip 6, while the damping, buffering group 7 of the inside setting of support base also can up and down
Enough that a certain range of displacement occurs in the longitudinal direction, the displacement of above two mode can absorb between fine strain of millet body and bridge pier because of longitudinal position
The vibration for moving and generating；
If horizontal displacement (when such as earthquake) has occurred between fine strain of millet body and bridge pier, due to depositing between upper support seat 4 and bridge
There are frictional force between frictional force, lower support base 1 and bridge pier, therefore upper support seat 4 can be with lower support base 1 in the horizontal direction
It being subjected to displacement, the relative displacement in certain horizontal direction can all occur between backing plate 8 adjacent thereto for each layer of backing plate 8,
Certain deformation can also occur for the spring 9 that the array between every adjacent two layers backing plate 8 is distributed simultaneously, and (axis of spring is by longitudinal direction
The straight line of distribution becomes inclined curve), under the action of these spring 9, the stress generated when displacement can be effectively absorbed, and
It allows between fine strain of millet body and bridge pier and returns to original state after external force removes；
At the same time, certain deformation can also occur for the vulcanie item 6 being clipped between upper support seat 4 and lower support base 1
(distortion), to adapt to above-mentioned relative displacement；And the state before being restored to deformation after fine strain of millet body and bridge pier return to original state.
Upper position sensor 10 and associated lower sensing battle array during above-mentioned movement occurs, in detection zone
Some sensor in column 11 can always detect the displacement in motion process；Longitudinal displacement can directly lead to
The measurement of upper position sensor 10 is crossed to obtain；And the displacement (translation or rotation) of horizontal direction can then pass through upper position sensor
10 motion profile during being displaced generation is converted to obtain,
Since lower sensor array 11 is made of the sensor that multiple arrays are distributed, it is able to detect that position passes
The motion profile of sensor 10 during the motion；It has been symmetrically arranged two sets of detection devices in each damping device, has passed through
The data of the two detection devices measurement, the computer in control system can judge upper support seat 4 relative to lower support
The horizontal movement amount or amount of spin of seat 1；And these data all have more important for bridge construction, maintenance unit
Guiding significance.
