Abstract

Abstract: Using hydraulics principle and experiential equation，diferent gutters and inlets are alalysed deeply.To gutter，the equation of single section and composite section to compute water flux is confirmed；To inlet，interception capacity afected by water flux in gutter，crofts slope，longitudinal slope and depressed gutter is considered.Based on the result，the interception capacities on grades ofdiferent inlets in diferent conditions are confirmed，and at last，the right type of gutter and inlet in pavement surface drainage design is commended.

摘要： 利用水力学原理及经验公式对不同形式的边沟以及不同形式的排水口进行了深人分析.对于边沟主要确定了具有单一横坡和复合横坡断面的水流量计算公式；对排水口，综合考虑了边沟内水流量、铺面横坡、纵坡、边沟内设置低洼区等因素对其排水能力的影响.确定了排水口在连续坡段上不同形式的排水口在不同条件下的截流率，从而得出了设计表面排水系统时连续坡段上宜采用的边沟和排水口形式.

To further study its influence mechanism and to solve the problem of limited accuracy of traditional prediction methods under multi-feature data conditions, a pavement skid resistance performance assessment model based on the fusion of Bayesian optimization algorithm (BOA) and extreme gradient boosting (XGBoost) was proposed. Firstly, specimens phalt mixtures of different gradation types were prepared. Friction data and 3D texture data of the specimen surface were respectively obtained by using a pendulum friction meter and a 3D laser scanning device. Secondly, the height, the wavelength and shape parameters were extracted to describe the texture structure, and the texture feature importance analysis was carried out to clarify the factors that significantly affected the skid resistance. Then, the optimal key parameters were improved by introducing of the model BOA-XGBoost and the prediction model of skid resistance performance was established. The research results show that compared with the comparative models, the proposed model has higher accuracy, with a correlation coefficient R2 of 0.890 6, which is 25.2%, 13.0%, and 15.1% higher than those of the comparative models, respectively. The proposed model can effectively correlate texture features with pavement skid resistance performance. [J]. Journal of Chongqing Jiaotong University(Natural Science), 2025, 44(6): 35-44.
