Risk Assessment of Bridge Construction Project Based on Fast ICA Algorithm

With the growth of China's economy, the scale of infrastructure construction is expanding, and the investment risk is also increasing. This paper establishes the risk rating model of bridge engineering project based on Fast ICA model. Firstly, this paper introduces the risk management of bridge engineering project, then expounds the concept, principles and methods of project safety risk identification, and then studies the appliance of fast ICA algorithm. Based on this, a series of related designs are carried out, and the risk identification simulation test of the model is carried out. Finally, the test results show that the risk assessment rate of the model for foundation pit, extreme weather, heavy tools, bridge quality and geological conditions is more than 75%, which shows that the risk assessment model of bridge engineering project based on Fast ICA algorithm can effectively assess the project, and the accuracy is very high, which can meet the needs of users. This article provides more theoretical basis for project risk analysis by evaluating the risk of bridge construction projects using the fast ICA algorithm, and plays an important role in reducing the risk of bridge construction projects and promoting the better development of bridge construction.
