【摘要】 由于缺乏评价基层施工质量的有效方法,导致基层施工质量处于失控状态。采用落锤式弯沉仪(FWD)评价基层模量的均匀性来反映基层施工质量。引入“车道内数据重复性标准偏差Sr,”“车道间数据重复性标准偏差SR,”“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”四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。更多还原

【Abstract】 There is few effective methods to evaluate road base construction quality,which caused it in an uncontrollable condition.falling weight deflectometer was used to evaluate the uniformity of the road base to reflect the construction quality."Repeatability standard deviation of the data in the same driveway—SR"," reproducibility standard deviation of the data in the different driveway—Sr","consistency statistics value of the data in the different driveway-h",and "consistency statistics value of the data in the same driveway-k" were introduced as the analysis methods.The result shows this method can reflect the road base construction quality fairly well.更多还原
