类比法在公路大气环境影响预测中的应用

Application of Analogue Method on the Highway Air Environmental Impact Prediction

通过类比法与扩散模型法预测公路大气环境影响的对比分析,对类比法在公路机动车排气污染方面的应用进行了深入研究,采用工程特征、污染物排放特征、环境特征相似的原型公路监测值的类比修正结果作为新建公路机动车尾气环境空气影响的预测值。计算实例表明:类比法预测结果误差小于扩散模型计算结果,类比预测结果更接近于验证结果。

The application of analogue method in the study of exhausting pollution of highway motor vehicles was investigated by comparative analyzing analogue method and diffusion model prediction. Correction of monitoring data from a similar engineering, pollution emission and environmental characteristics archetypal highway was regarded as the air environmental impact prediction value of the newly-built highway motor vehicle exhaust. It is revealed that analogue method has minor prediction error compared with diffusion model calculation, which means the analogy method prediction approaches the verification result better.
