摘要:研究目的：目前，我国绿色施工的相关评价体系的研究相对匮乏，尚未形成一套完整的绿色施工评价体 系，绿色高速铁路施工评价的研究也同样处于探索阶段。本文提出突变级数法，并参照我国绿色施工相关规 定，探讨适合我国国情的绿色高速铁路施工评价方法，从而为规范我国绿色高速铁路施工评价提供理论支撑。研究结论:( 1)对绿色高速铁路施工方案评价目标进行多层次分解，将底层评价因素进行无量纲化处理、归一化处理，运用不同突变模型的归一公式进行计算，得到突变级数值，给出最优评价结果;（ 2)实例研究表 明，突变级数法可避免人为确定权重的主观性，且计算简单、可靠性高，评价结果更趋于实际；（3)本研究成 绿色高速铁路施工评价提 参 。

Abstract:Research purposes ： At present， the evaluation criteria and metliods for green construction are absent in China，and the research of green high - speed railway construction is still ongoing. According to the actual situation in our country，this paper discussed the establishment of a set of evaluation criteria for green construction of high - speed railway based on catastrophe progression method，which has a strong guiding role to regulate the green construction of high - speed railway in our country. Research conclusions:( 1) The multi - layer evaluation objects were analyzed in this metiiod，and standard quantization of bottom evaluation indexes was performed. Then，the ultimate catastrophe function was obtained through quantitative computation by the normalization formula of different catastrophe models. Lastly， the comprehensive evaluation of alternative was realized. ( 2 ) The result of an evaluation example indicates that the presented method can not only avoid the subjective quantification of assessment indexes， but also be easy to perform and obtain high reliability， which improved the practicability of the catastrophe progression metiiod. (3) The research results can provide a theoretical reference for green construction evaluation of high - speed railway.
