摘要
随着我国高铁的不断发展,需要对其施工质量风险进行研究。借鉴5M1E分析法选取风险评价指标体系,通过采样得到的数据,利用熵值法确定每一项指标的权重。多次计算权重并且对数据的稳定性进行检验,根据标准差可判断数据是较为稳定的。对高铁项目施工质量风险程度进行综合评价,分析评价结果,从高铁新材料和新技术两大方面提出了相应的建议。
With China's high-speed rail development,it is necessary to research on its construction risk.Firstly,a risk assessment system was established according to 5M1E analysis.Secondly,based on the entropy method,the weight of each indicator were determined with the data obtained by sampling.Through calculating weight many times and testing the data's stability,we judge the data is stable by standard deviation.Thirdly,a comprehensive risk evaluation system of high-speed rail project construction quality was built.Some suggestions from new materials and new techniques are presented.
