摘　　要：采用移动式采样法,于2014年秋季、冬季和2015年春季、夏季采集了石家庄4种道路类型(快速路、主干道、次干道和支路)两侧的快、中、慢车道的积尘,分析了不同季节、不同道路类型、不同速度车道以及不同方向车道的积尘负荷分布特征。结果表明:4个季节的平均积尘负荷为秋季0.111g/m^2、冬季0.027g/m^2、春季0.055g/m^2、夏季0.046g/m^2;不同道路类型的平均积尘负荷为快速路0.084g/m^2、主干道0.038g/m^2、次干道0.043g/m^2、支路0.048g/m^2;不同速度车道平均积尘负荷为快车道0.039g/m^2、中车道0.048g/m^2、慢车道0.079g/m^2;不同方向车道积尘负荷差别不大,且大体上显著相关,说明主导风向对道路积尘的影响不大,而车流量的影响较大。3 lanes(fast,medium and low)of both sides of express road,trunk road,secondary trunk road and branch road in Shijiazhuang were selected as sample roads,and mobile sampling method was chosen for silt collection from autumn 2014 to summer 2015.Silt loading distribution characteristics of different seasons,different road types,different velocity lanes and different direction lanes were analyzed.Results showed that silt loading of autumn was 0.111 g/m 2,that of winter 0.027 g/m 2,that of spring 0.055 g/m 2 and that of summer 0.046 g/m 2.Silt loading of express road was 0.084 g/m 2,that of trunk road 0.038 g/m 2,that of secondary trunk road 0.043 g/m 2 and that of branch road 0.048 g/m 2.Silt loading of fast lane was 0.039 g/m 2,that of medium lane 0.048 g/m 2 and that of low lane 0.079 g/m 2.Silt loading of different direction lanes had little difference but had significant correlation in general,indicating that main wind direction had little effect on silt loading but vehicle flow rate had great effect.
