摘要
通过大量的便携式落锤弯沉仪P(FWD)与贝克曼梁的现场对比试验,研究了PFWD弯沉与贝克曼梁弯沉的关系,得出两种弯沉之间存在良好的线性相关关系。结果表明PFWD可作为新型的路基承载力的快速检测和评价技术。
Through a great deal of contrast tests of portable falling weight deflectometer（PFWD） and Beikeman beam, the paper gives satisfactory linear correlation of two kinds of deflection. The result shows the PFWD can be as a new technology of measuring and evaluating the subgrade capacity.
