Such methods as analytic hierarchy process （AHP） , Delphi method and fuzzy comprehensive evaluation method are adopted to make the quantitative analysis on the risk factors and establish the risk judgment model. According to the actual engineering of Taizhou Bridge, the paper evaluates the risk of the foundation during the operating period at the condition of deep overlying stratum. The evaluation results can provide the reference for the risk management of the bridge foundation durin~ the ooerating period.展开更多

This study emphasizes the connection between theory and practice in research frame. It is intended by this research using content analysis of UI GreenMetric, universities＇ websites and sustainability annual reports observing universities＇ practices related to sustainability to answer the research question, which is： How are university managements embedding sustainability-oriented practices in sustainability focused European universities as far as CORE system （Curriculum, Operations, Research, and Engagement） is considered？ The employed research methodology mainly relies on content analysis of the studied universities from the UI GreenMetric Sustainable University assessment and ranking index. The UI GreenMetric Sustainable University assessment and ranking index was selected since it considers the Operations, Curriculum, Research, and Engagements （CORE system） of universities with indicators such as Setting and Infrastructure, Energy and Climate Change, Waste, Water, Transportation, and Education. This covers the triple bottom line of sustainability （Environment, Economy, and Society） and other indexes like GASU, AASHE, STARS and others, focused mostly on operational Eco-efficiency. UI GreenMetric index is the first and the only ranking that measures each participating university＇s commitment in developing an ＂environmentally friendly＂ infrastructure. The total sample of the study observed and evaluated in this study are five （5） top European Sustainable Universities according to UI GreenMetric sustainable ranking index. The result shows a significant progress in Operational practices except in the area of Campus Setting and Infrastructure. There was a less significant progress in the Curriculum, Research, and Engagement practices of the CORE system of sustainability-oriented practices which are being integrated into the studied universities. This research provides a state of the art result regarding the embeddedness of sustainable practice in European universities. It has the potential to help any university to better integrate sustainability in their management system.展开更多
