| Abstract: | Combined with comparison test on deflection between FWD and Benkelman beam, by analysis on the work principle of FWD and its characteristic the deflection detection distance that the different detection aims should be in accordance with is studied. And the article proves that under the same detection situation not only FWD has good relation with deflection detection value of Benkelman beam but also FWD has advantages of rapid speed and high accuracy. |
