ABSTRACT

The paper evaluates the influence of dynamic effects filtration incorporating the method of deflection frequency normalisation on the results of the comparative analysis of FWD dynamic instruments. The authors' calculations are based on a database comprising the results of comparative deflection tests conducted by use of six FWD instruments, on five different test sections, in strictly monitored on-site conditions. After analysing the results of deflection measurements subjected to the dynamic effects filtration procedure, it was possible to unambiguously determine the device for which the obtained deflection values differ most from the values obtained for other devices. The unequivocal selection of a device for comparative test results of FWD devices that had not been submitted to deflection frequency normalisation has not been possible. The calculations performed in the paper have confirmed the positive influence of dynamic effects filtration using the method of deflection frequency normalisation on the results of the comparative analysis of FWD devices.

摘要

本文评估了结合偏转频率归一化方法的动态效应过滤对FWD动态仪器对比分析结果的影响。作者的计算基于一个数据库，该数据库包含使用六台 FWD 仪器在五个不同的测试部分在严格监控的现场条件下进行的比较挠度测试的结果。在分析了经过动态效应过滤程序的挠度测量结果后，可以明确地确定获得的挠度值与其他设备获得的值差异最大的设备。不可能明确地选择一个设备来比较未提交偏转频率归一化的 FWD 设备的测试结果。
