Position index bridge floor test system.
Background technology
Pointing out in " Highway Bridge load testing regulations " JTG/T J21-01 2015, Test on Bridge Loading is by applying
The on-the-spot experimental test that quiet, the dynamic trait of bridge structure or component are carried out by load mode.Try including static test and dynamic load
Test.Static test Static Parameter preferably includes straining (stress), displacement, crack, inclination angle and rope (bar) power.Displacement be reaction test across
The important indicator of the existing bending rigidity of bridge, for bridge structure technology status and Bearing Capacity Evaluation and maintenance in the future, keeps in repair, adds
Solid decision-making scientific basis and support are provided.
Displacement index measurement has following several method at present: dial gauge is measured, precision level is measured, gps satellite location
Systematic survey etc..
Displacement surveyed by dial gauge is to use rigid connecting rod, connects bridge tested point and the motionless rock stratum at the bottom of bridge, in measuring staff
Between seal in dial gauge, thus reach to measure the purpose of deflection of bridge span.This mode must set up fixed support under bridge, and only fits
Close the bridge on dry river or the shallower river of water.
The mode of displacement measured by precision level is to be placed in by level gauge in the reference point (such as bridge pier or end of the bridge) of bridge, so
After water level box staff is placed in the tested point of bridge, tested the displacement of bridge by the straight line principle of light.The method is simple and convenient, precision
Higher, be method most commonly used in Test on Bridge Loading, but the method can only manual measurement, measuring speed is relatively slow, people
For big with such environmental effects, and cannot realize automatically measuring.
Gps satellite alignment system is to utilize satellite fix tested point, directly reads the coordinate of measuring point, the method certainty of measurement
Low, the monitoring accuracy requirement of some amount of deflection change bridge type (such as super-huge suspension bridge etc.) the most greatly can only be met, and cost is relatively
High.
In sum, in above conventional test common method, dial gauge surveys displacement by environmental effect under bridge relatively greatly, and also needs
Support to be set up；It is slower that displacement measuring speed measured by precision level, it is impossible to realizes automatically measuring；Gps satellite alignment system, surveys
Accuracy of measurement is low, relatively costly.
