Study on Safety and Durability of Civil Structural Engineering Based on System Dynamics
The continuous expansion of civil engineering scale has greatly promoted the process of urbanization and the rapid development of China's economy. In the design of civil structure engineering, the study of its safety and durability is very important, which determines the quality level of the project. However, the level of safety setting in terms of safety and durability is generally lower than that of similar foreign standards, which should be paid enough attention by relevant authorities and design and construction units in China. In order to ensure the safety and durability of civil engineering, it is necessary to do a good job in the quality management of civil engineering, and to supervise and review all stages of civil engineering construction. Make clear the inspection of the project and the normal maintenance and repair system, and gradually dilute the mandatory nature of the technical specifications in the preparation, revision and management of technical standards. Using system dynamics to fully demonstrate and analyze the construction safety cost index and safety impact factor system has positive practical significance and effect on the further development of civil engineering safety and durability.
