APPARATUS FOR LOADING TEST OF RAILROAD BRIDGE, METHOD FOR CALCULATING LOAD CARRYING CAPACITY OF RAILROAD BRIDGE AND METHOD FOR MEASURING DROOPING OF RAILROAD BRIDGE

摘要

PURPOSE: A loading laboratory device of a railway bridge, a load carrying capacity calculation method of a railway bridge using the same, and a slack measurement method thereof are provided to calculate actual substantial load carrying capacity of the bridge by train load. CONSTITUTION: A loading laboratory device of a railway bridge comprises a Wheel load measuring gauge unit, a wheel load measuring device(200), and a lateral force measurement gauge unit. The wheel load measuring gauge unit comprises a strain gage for measurement among multiple wheels. The strain gage is arranged in a web of a rail(40) in right and left. The wheel load measuring gauge unit outputs voltage when a rail is deformed by the wheel load of the train. The wheel load measuring device comprises a fixing equipment. The lateral force measurement gauge unit outputs voltage when a rail is deformed due to the lateral force of the train. The lateral force wheel load measuring device comprises a pair of holders.
