基于面层渗透系数的路表水渗入率设计

Design of road infiltration based on infiltration coefficient of pavement

摘要: 根据对渗入率设计指标的分析,一定损坏状况的路面渗透系数是影响路表水渗入率大小的关键。为此,本文经过对透水面层下设透水层的渗流理论的分析,建立了该种条件下的渗入率设计模型,并根据测试数据标定了模型参数,确定了不同养护等级的渗入率计算方法。

Abstract: Based on the analysis of the criterion of road infiltration,it was the pavement infiltration on some damage condition which affected the road infiltration.Therefore,through the analysis of the theory of permeable pavement based on permeable base layer,the design model of road infiltration was established.The parameter of the model was calibrated by the test data,and the method to calculate road infiltration was then determined.
