Analysis of the Influence of Bridge Pile Construction on Oil and Gas Pipelines

With the large-scale construction of infrastructure such as highways and railways, the construction of infrastructure will inevitably have adverse influences on the normal use and safe operation of adjacent buried pipelines. Once an oil and gas pipeline leakage accident occurs, it will lead to huge economic losses and even casualties. This paper uses FLAC3D finite element software establish the bridge pile-pipeline soil mass model, and simulates the influence of bridge pile construction on the stress and deformation of nearby oil and gas pipelines. The research results indicate that after the construction and operation of bridge piles, their influence on the stress and displacement of the soil around the pipeline is relatively small, and they will not cause major safety hazards.
