Gas Transmissions Seismic Transient Response Simulation and Installation Design in Shield Tunneling

摘要

This paper use commercial software to simulate the gas transmissions seismic transient response and stress distributions, assuming that the shield tunneling field experiences 8 degree seismic fortification intensity. The simulation offers an useful guideline for gas pipelines installation design. It also provides some key conceptual installing designs, such as enough gap between pipes and support, and water filling in all tunnel shaft.
