Research on The Techniques of Dynamic Testing for Taxiway Bridge under Aircraft Taxiing

摘要

To resolve traffic conflicts, taxiway bridges are set in major airports. Taxiway bridges are different from highway bridges in load grades and structure types. The traditional test methods are short in two aspects: interrupting traffic, which seriously affects the normal operations of airport. And the second is all of them can not simulate actual load of aircraft to taxiway bridge. This paper gives a brief introduction to the technical research on mechanical properties of taxiway bridge, which is based on modal tests and aircraft loading tests. The result shows that this method can overcome the shortcomings of traditional test methods, and provides an effective method for rapid non-destructive testing on taxiway bridges.
