摘要
针对目前水泥路面脱空状况评定方法中方法单一,不同评定方法的结果差异较大,主观影响因素过多等问题,根据影响脱空状况的板角最大弯沉、FWD截距、FWD斜率、接缝传荷系数等指标,提出了一种基于物元模型的水泥路面脱空状况综合评定方法,以水泥路面脱空状况、评价指标及其特征值构造物元模型,并根据计算出的综合关联度实现对各水泥路面脱空状况的综合评定。实例表明该模型能更准确、更综合的反映路面脱空状况,具有一定的推广应用价值。
As the evaluation method for cement concrete road void is single, different evaluation method may lead to different results, and there are more subjective factor in the course of evaluation, a new evaluation system based on matter- elements -analysis has been developed based on such evaluation indexes as board comer biggest deflection, intercept of FWD, slope of FWD and joint load transfer coefficient. The characteristic values can be calculated to reveal their synthetic relation degrees. According to those values and degrees, the void condition can be evaluated accurately. Application results show that this method is scientific and reliable.
