过水围堰初期导流费用风险率计算模型研究

Study on the Calculating Model of Diversion Cost Risk of Overtop Cofferdam in First Stage

针对过水围堰初期导流费用的构成及其随机特性，首次提出了费用风险率的概念并给出了研究费用风险率的计算模型，从而为施工导流风险设计提供科学的依据．

Aiming at the composition and random characteristic of the diversion cost of overtop cofferdam in first stage, this paper first puts forward the concept and the randomcalculating model of cost riskratio. It provides the scientific basis for construction diversion riskdesign
