摘要
通过对落锤式弯沉仪法(FWD)与贝克曼梁法(BBD)进行对比分析,结果表明,FWD法在精度、稳定性和检测效率方面优于贝克曼梁式弯沉仪法,且FWD法与贝克曼梁法测得的路面弯沉值存在较好的线性关系。
Comparing the falling weight deflectometer test method with the Benkleman beam deflectometer test method, the result indicated that the falling weight deflectometer test method is superior to the Benkleman beam deflectometer test method on the precision, stabilization and efficiency. On the other hand, there is good linear relation between the falling weight deflectometer test method and Benkleman beam deflectometer test method.
