Strength Failure of a Natural Gas Station Pipe System under Foundation Settlement and Countermeasures
Year: 2025
Type: article
Abstract: The foundation settlement is one of the potential hazards that causes stress concentration in natural gas station pipes and their bending deformation.This paper deals with the on-site foundation settlement of a natural gas station.A set of three-level early warning schemes was proposed for the foundation settlement in the natural gas station.In addition, a countermeasure method was also proposed.Results show that the stress is concentrated at the bend of the gate-shaped pipe and the connection between the gate-shaped pipe and the main pipe.The gate-shaped pipe exhibits inclined deformation.The method of installing a concrete floor under the pipe can effectively reduce stress concentration at the connection between the gate-shaped pipe and the main pipe.If pipe piers are used for support, the stress and displacement of the pipe can be reduced to a certain extent, but the impact is limited, and the effect is slightly better when both ends and the middle of the pipe are supported.
