Description

Background Art

[0002] The construction of oil and gas pipelines has entered a peak period, and the total mileage of pipelines has shown explosive growth. In view of the rapid development of the region and safety considerations, long-distance pipelines are currently mostly laid in mountainous areas; considering the damage to the ecological environment caused by the construction of long-distance pipelines, the built pipelines usually use tunnels to pass through the mountains. In order to achieve a wide coverage and diversified structure of the oil and gas pipeline network system, taking into account the uniqueness of the pipeline route, the protection of the ecological environment and the economy of the project investment and other key factors, it has become a trend to use existing tunnels to lay new pipelines.

[0003] The mountain tunnel of oil and gas pipeline is mainly composed of the external environment, the tunnel body, and the existing facilities in the mountain tunnel. Among them, the existing facilities in the mountain tunnel are the key factors affecting whether the tunnel can be reused. Therefore, conducting a study on the suitability evaluation of the reuse of the existing facilities in the mountain tunnel is of vital importance to promote the safe, economical and stable operation of the pipeline in the mountain tunnel.

[0004] At present, the current evaluation methods for the suitability of existing facilities in mountain tunnels are mostly based on specific engineering cases. Through simple geometric calculations, suggestions are provided for existing facilities in mountain tunnels under certain working conditions. There is a lack of a universal evaluation system based on data and scientific research methods. There are almost no literature and patents on the evaluation methods for the suitability of existing facilities in mountain tunnels, and there is no mature evaluation method for the suitability of existing facilities in mountain tunnels. Therefore, it is urgent to form patent results for new evaluation methods for the suitability of existing facilities in mountain tunnels to provide solutions for engineering.
