使用落锤式弯沉仪评价基层施工质量均匀性(英文)

Evaluating base course uniformity using falling weight deflectometer

长期以来由于缺乏评价基层施工质量的有效方法,导致基层施工质量在某种意义上讲处于失控状态。本文尝试使用落锤式弯沉仪(FWD)评价基层模量的均匀性来反映基层施工质量。引入“车道间数据一致性统计量h”和“车道内数据一致性统计量k”两个统计量作为分析手段。结果证明这一方法较好地反映了基层施工质量均匀性。

For a long time, the short of effective methods for evaluating course construction quality results its uncontrollable state. In this paper, falling weight deflectometer （FWD） was used in evaluating the uniformity of the base course to reflect the construction quality. Consistency statistics values of intra- lane and inter-lane data, k and h, were introduced as the analyzing parameters. It was showed that this method was effective in evaluating uniformity of the base course construction quality.
