【摘要】 为了进一步完善我国公路建设中的路基施工质量均匀性评价方法,提高对公路路基施工质量的监管水平,本文首次将曲面拟合的方法引入路基评价领域,通过对实测数据进行光顺化处理,减弱因测量所引起的随机误差对评价结果的影响,并在此基础上,提出了伪方差-均值综合评价法。随后的随机模拟及工程实证表明:对于特定填料的路基及事先给定的模量设计值μ*,所提评价方法能够对路基的实际情况做出客观评价,并得到一总体评价值GD(f~,μ*)。更多还原

【Abstract】 In order to further consummate the method that assessing the uniformity of the highway roadbed construction quality and enhance its supervising and managing level in China,the curved surface fitting method was applied to roadbed assessing for the first time.This new method which is an improvement to the existing method can smooth the measured data,thus weaken the influence of random measured error on the assessing result.Based on this work,the method of pseudovariance-average synthetic evaluation was proposed which could carry on the overall evaluation of uniformity of the roadbed.The succdent random simulations and the project real-example diagnosis shows that this method can make an objective evaluation to the actual road surface situation and obtain an overall appraisal value GD(f～,μ*)regarding specific padding material and roadbed module design value μ*.更多还原
