| Abstract: | The working mechanism of the deflection tester in bridge inspection is to transform the changes of liquid-air coupling pressure difference to the variation of bridge deflection.In the bridge inspection in Shenyang,the deflection tester is used to test the vertical deflection of bridge.By way of examples of the Deflection test of the main bridge of Sanhao Bridge,the deflection inspection of the hollow slab of the 5th span of the north approach bridge of Dacheng Bridge and the residual deflection test of the main bridge of Gonghe Bridge,the measured values and calculated values were compared and analyzed.The results indicate that the testing results meet related requirements,the tester is characterized by easy installation,rapid and precise testing,which satisfy the requirements of inspection with high speed and high degree of precision for city bridges. |
