公路工程绿色施工能够有效减少资源消耗和环境污染,越来越受到重视和发展,对公路绿色施工系统进行科学客观评价是公路施工系统研究的重要一环。根据公路施工系统与热力学系统特征的相似性,分析了公路施工系统的耗散特征,并定义了施工熵、施工负熵和施工总熵概念;根据公路绿色施工系统的影响因素,建立了绿色施工评价熵指标体系;根据信息熵模型建立了基于负熵理论的公路绿色施工评价模型,并将熵指标体系和模型进行了案例应用。应用结果表明:基于负熵理论的公路绿色施工评价方法能够评价不同施工技术的绿色程度;同时,可以将施工系统中拥有不同量纲的各种影响因素统一计算成施工熵,便于分析评价。
Highway construction green construction can effectively reduce resource consumption and environmental pollution, more and more attention and development, scientific and objective evaluation of highway green construction system is an important part of the highway construction system research. According to the similarities between the highway construction system and the thermodynamic system, the dissipative characteristics of the highway construction system are analyzed and the concepts of construction entropy, construction entropy and construction total entropy are defined. According to the influencing factors of highway green construction system, the green construction The entropy index system was evaluated. According to the information entropy model, the green construction evaluation model of highway based on negative entropy theory was established, and the entropy index system and model were applied case by case. The application results show that the evaluation method of highway green construction based on negative entropy theory can evaluate the green degree of different construction techniques. At the same time, various influencing factors with different dimensions in construction system can be uniformly calculated as construction entropy for analysis and evaluation.
