铁路隧道绿色施工评价研究
Evaluation Study on Green Construction of Railway Tunnel

为解决铁路隧道施工对环境造成的严重威胁，有效推进绿色施工在铁路隧道施工中的应用，本文提出基于改进Vague相似汇总理论的评价方法。依据PSR(压力–状态–响应)框架模型，结合指标构建绿色建筑评价体系的三个原则，从指标生成机制方面构建绿色建筑评价指标体系；然后利用C-OWA算子进行赋权，削弱专家主观偏好的影响，利用改进的Vague集构建绿色施工评价模型，将专家主、客观权重和Vague值相结合，对隧道工程绿色施工进行评价；最后，在兰新铁路二线祁连山隧道工程绿色施工评价模型中进行了应用，验证了模型的合理性和可行性。
In order to solve the serious threat to the environment caused by railway tunnel construction and effectively promote the application of green construction in railway tunnel construction, this paper proposes an evaluation method based on improved Vague summary method. First, relying on the Pressure-Status-Response(PSR) framework model, combining the three principles of the index to establish a green construction evaluation system, the green construction evaluation index system is established from the perspective of the index generation mechanism; second, the evaluation index is assigned through the C-OWA operator Weight, thereby weakening the influence of experts ’subjective preferences, and using the improved Vague set similarity aggregation method in the construction of green construction evaluation models, combining expert subjective and objective weights and Vague values to judge the green construction grade of deep foundation pit projects; Applying the green construction index system and evaluation model to the Qilian Mountain Tunnel on the second line of the LanXin Railway, which proves that the evaluation model is reasonable and feasible.
