With the progress of science and technology, the development of sensor technology provides strong support for real-time monitoring and early warning. By accurately monitoring the propagation of seismic waves and the dynamic response of the pipeline, we can better understand the behavior of the pipeline in the earthquake, and design and optimize the seismic reduction accordingly, thus improving the seismic capacity of the pipeline system. In this study, the seismic design and optimization of gas pipeline under earthquake time effect are discussed in depth. In this study, an optimization algorithm based on sensor data is proposed, which combines genetic algorithm and neural network to achieve the best shock absorption effect. Through integrated sensor technology, the stress change of gas pipeline during earthquake is monitored in real time, with special attention to the stress concentration phenomenon at the pipeline interface and the inner side of bending. The experimental results show that the stress in these key areas can reach 250MPa under the action of earthquake, which seriously threatens the pipeline safety. Therefore, various seismic design methods are adopted for optimization, and the maximum stress is successfully reduced to 160MPa, which significantly improves the seismic performance of the pipeline. This study not only provides a scientific basis for the shock absorption design of gas pipelines, but also lays a solid foundation for ensuring the safety and efficiency of energy transportation.
