摘要
旨在研究铁路路基爆破的"资源效率—环境效率—经济效率""三位一体动态爆破综合效益率"。基于绿色施工理念和传统Malmquist模型,以爆破工程为研究主体,引入环境负产出要素,充分考虑资源投入的利用率和动态投入的长远效应,建立铁路路基爆破Malmquist模型(BMPI)。选取25个决策变量作为模型的基本要素,运用改进最小熵模型进行权重赋值;基于DEA-SOLVER PRO软件平台进行BMPI的爆破全要素生产率及其分解效率的测算,同时根据前人研究给出各要素的冗余率分析。最后通过实例分析给出"绿色施工促进爆破综合效益率"的结论。
        In order to study resource efficiency-environment efficiency-economic efficiency,trinity dynamic blasting comprehensive efficiency rate of railway subgrade blasting engineering.Based on the green construction concept and the traditional Malmquist model,the blasting project was taken as the main body,the negative environmental output factors were brought in,and the utilization of resources and the long-term effects of dynamic inputs were fully considered,then the Malmquist model for railway subgrade blasting(BMPI) was established.25 decision variables as the basic elements of BMPI were selected,and the improved minimum entropy model was used for weight assignment.Then BPMI′s blasting TFP and its decomposition efficiency were calculated based on the DEA-SOLVER PRO software platform.At the same time,based on previous research,the redundancy rate of each element is analyzed.Finally,the conclusion that "green construction promotes the comprehensive benefit rate of blasting" is given through a case study.
