【摘要】：為了探明公路路面積水(積雪)過程和干濕狀況的變化及其氣象因子的影響,以江蘇省金壇試驗基地試驗路段的道路氣象數(shù)據(jù)作為模型輸入數(shù)據(jù),利用改進的Sass道路積水物理模型對3次降雨(雪)過程中的道路積水量進行模擬,通過對模型模擬結果的分級和與儀器記錄、人工觀測結果的對比,驗證模型模擬路面狀況的準確性,并探討了氣象因子對路面積水量的影響。研究結果表明:(1)改進的Sass模型可用于對道路干濕狀況的模擬,且準確性較高,可推廣到高速公路路面狀況的實時監(jiān)測和預報;(2)排水過程中,徑流和蒸發(fā)在不同時期對排水量的貢獻率差異較大,從總量上講,徑流對排水起了主要作用;(3)氣象因子對道路積水的影響主要體現(xiàn)在降水量直接影響道路積水,而其他氣象因子則通過對蒸發(fā)量的影響來間接影響積水量。
[Abstract]:In order to find out the changes of water accumulation (snow cover) process, dry and wet conditions and the influence of meteorological factors on highway pavement, the road meteorological data of the experimental section of Jintan Test Base in Jiangsu Province were taken as the input data of the model. The improved Sass physical model is used to simulate the amount of road water accumulated in the course of three rainfall (snow). The simulation results are compared with the results of manual observation and the classification of the simulation results. The accuracy of the simulation model is verified, and the influence of meteorological factors on the water volume of road area is discussed. The results show that the improved Sass model can be used to simulate the dry and wet conditions of roads, and the accuracy is high, which can be extended to the real-time monitoring and forecasting of highway pavement condition. The contribution rate of runoff and evaporation to water displacement varies greatly in different periods. In terms of total amount, runoff plays a major role in drainage. (3) the influence of meteorological factors on road water accumulation is mainly reflected in the direct influence of precipitation on road water accumulation. Other meteorological factors indirectly affect water accumulation through the influence of evaporation.
