Abstrait:

Due to the relatedness of the risk events in infrastructure, this paper attempts to give the correlation mechanism of the risk events, and abstracts the correlation structure into a risk chain-model. At the same time, based on the risk chain-model, the process and approach of the ecological, disaster and safety risk assessment during the bridge construction are proposed. Taking the railway bridge across the Nairobi national park as an example, this method is applied to the risk assessment study during the bridge construction, and the probability level, the loss expectation and the risk level of every risk category are given. The results show that this method is more systematic and comprehensive for the risk sensitive construction management, ecological environment and natural disasters. The evaluation method proposed in this paper has important practical application value for the risk evaluation of the infrastructure in ecologically sensitive areas.
