摘　　要：提出静态和动态荷载双重作用下开展路面沉降分层监测分析的方法,利用激光扫描仪获取路面数据,构建路面数据模型;分析静态荷载和动态荷载下的路面沉降色谱,通过概率函数因子加权处理计算双重荷载下路面沉降观测权重;通过静态荷载和动态荷载双重作用下的数值模拟分析,评估道路沉降的趋势和程度。结果表明:此方法在静态荷载下的监测沉降量与实际沉降量误差低于0.02 mm,在动态荷载下的监测沉降量与实际沉降量误差低于0.04 mm,可为不同的荷载情况(静态和动态)道路沉降量监测提供依据。A method of stratified monitoring and analysis of pavement settlement under the dual action of static and dynamic loads is proposed.The road surface data was obtained using a laser scanner and a road surface data model was constructed.The chromatography of road surface settlement under static and dynamic loads was analyzed.The weight of road settlement observation under dual loads is calculated through probability function factor weighted processing.Evaluate the trend and degree of road settlement through numerical simulation analysis under the dual effects of static and dynamic loads.The results show that the error between the monitoring settlement under static load and the actual settlement is less than 0.02 mm,and the error between the monitoring settlement under dynamic load and the actual settlement is less than 0.04 mm.It can provide the basis for monitoring of road settlement under different load conditions(static and dynamic).
