摘要
通过对FWD工作原理及其特点的分析 ,结合弯沉对比试验 ,研究了不同检测目的所对应的弯沉检测间距。证明了在相同的测试状况下 ,FWD与贝克曼梁的弯沉测定值之间不但具有良好的相关关系 ,而且速度快 ,精度高。
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.
