Application of Risk Assessment Methods in the Construction Phase of Large-Span Bridges

The construction of large-span bridges represents the technological level of bridge construction in a country, and plays a positive role in the country's economic development and technological advancement. However, there are many problems in the construction of large-span bridges, such as wind vibration during the construction phase, management of personnel, equipment, and materials, and environmental impacts during the construction period. Applying risk assessment methods to the construction phase of large-span bridges can effectively solve these problems, and risk assessment provides scientific basis for bridge design optimization, construction decision-making, and operation and maintenance management, improving the safety and durability of large-span bridges, and has important theoretical value and practical significance for ensuring the sustainable development of bridge engineering. This article analyzes the application of three cutting-edge risk assessment methods in the construction phase of large-span bridges through examples. The current risk assessment methods still have certain limitations, and this article explores and reflects on the future development direction of risk assessment systems.
