摘要
论述了负温混凝土工程冻害风险识别方法 ,并简述了Delphi方法及关联树法的原则 ,从防冻投资、减灾费用、冻害损失三个方面简述了冻害风险估计方法 ,并具体评价了负温混凝土工程冻害风险中常用指标。
The discriminations of freezing disaster risk of concrete engineering at minus-temperature and Delphi's method and related tree method are presented in this paper.The method of disaster risk assessment is described by three ways of invest,cost and loss for freezing concrete,and the six indexes of disaster risk evaluation for concrete engineerings at minus-temperature are given.At last,the model and the step for disaster risk management and decision-making are briefly introduced.
