The Study On The Optimization Of Bridge Engineering Insurance Rate Set Based On Bridge Construction Riskassessment

With the rapid development of economy in our country, the bridge as the hub part ofhighway traffic has an important meaning for the steady and rapid economic and socialdevelopment. Natural disasters or other accidents will cause very serious consequences, whenit happened in the bridge. How to prevent the happening of the accidents and reduce the lossafter accidents is very important for bridge construction management enterprise. From theexperience of developed countries, engineering insurance could stop loss and transfer the riskeffect and we should attach importance to research of bridge engineering insurance.Construction safety accidents accounted for a large proportion in all the accidents. In thispaper, it carried out the study of bridge engineering insurance rate set based on the bridgeconstruction process of risk assessment results. Paper is divided into the construction riskassessment research and bridge engineering insurance rates set. This method that is based onthe results of the fuzzy comprehensive evaluation modifies the original bridge engineeringinsurance rate. This method is applied in engineering example.1. On the basis of arrange fully knowledge of characteristics and classification aboutbridge construction risk, it carried out the study of bridge construction risk identificationmethods. It put forward the bridge construction risk identification process and establishes abridge engineering project risk list.2. Through the risk probability estimation in engineering project risk estimate and riskloss estimation research, it establishes the risk probability grading standards and risk lossstandards. According to project risk evaluation aim and evaluation criteria, it analyzes projectrisk through a variety of risk evaluation method.3. It sums up five kinds of commonly used engineering insurance rate calculation methodand put forward the method based on risk assessment results of increase and decrease todetermine the engineering insurance rate during bridge construction.4. The bridge construction risk identification, risk evaluation and the engineeringinsurance rate set method is applied to the practical bridge project. It achieve the wholeprocess of determining the engineering insurance rate during the bridge construction.
