摘要
针对路面抗滑性能评价指标单一、常权权重评价方法的局限性,无法准确反映路面抗滑等级,导致养护不及时,进而造成安全问题,提出了一种新的路面抗滑性能评价方法。该方法基于“惩罚-激励型”变权模型,综合考虑了横向力系数SFC、构造深度TD和摆值BPN多个评价指标,并通过使用惩罚-激励型变权原理计算了动态权重,优化了常权权重评价方法,建立了一种融合多个评价指标的基于变权模型方法的路面抗滑性能综合评价指标。以临金高速公路临安—建德段工程第TJ01标段路段为例进行了路面抗滑性能综合评价,将常权权重综合评价和变权权重综合评价所得结果与实际情况进行比较,结果表明变权权重综合评价是可行的,更符合实际路面抗滑情况。
A new method for evaluating pavement anti-skidding performance is proposed to address the limitations of a single evaluation index and a constant weight evaluation method,which cannot accurately reflect the level of road surface skid resistance,resulting in delayed maintenance and safety issues.Based on the“penalty incentive”variable weight model,this method comprehensively considers multiple evaluation indicators such as sideway force coefficient(SFC),texture depth(TD),and pendulum British pendulum number(BPN).The dynamic weights is calculate by the penalty incentive variable weight principle.The constant weight evaluation method is optimized.And a comprehensive evaluation index for road anti-skid performance is established,which is based on the variable weight model method that integrates multiple evaluation indicators.Taking the TJ01 section of the Lin’an Jiande section of the Linjin Expressway as an example,a comprehensive evaluation is conducted.The obtained results are compared with the actual situation.The results show that the variable weight comprehensive evaluation is feasible and more in line with the actual road surface anti-skidding situation.
