Risk assessment of bridge construction stage based on FCE

In order to control the key point of accidents during bridge construction, a number of major risk factors are recognized from the point of the insecure elements of human beings and the insecure status of objects, and a risk assessment index system of bridge construction stage is created based on these risk factors; so given the uncertainty and fuzziness of the risk factors, the risk assessment of the bridge construction stage based on FCE is created, this model determines the weight and the membership of the risk factors according to risk occurrence probability and risk loss; by the end, for Taizhou Bridge under construction, this article determines its risk factors in construction stage, and uses this model to judge its risk level. It is shown that the model can assess the risk of bridge construction stage with relative accuracy.
