Abstract: Rationality and correctness in the trenchless crossing method selection for large-diameter long-distance oil and gas pipeline are related to duration, cost and success of the entire project. Limitations and adaptability of three common trenchless crossing methods such as horizontal directional drilling, pipe jacking and shield-driven tunneling are analyzed in terms of geological conditions, crossing length and pipe diameter, pipeline protection and maintenance, construction efficiency, economy and limitations, and general selection principle are provided.If geological conditions are suitable, directional drilling crossing method will be preferred, followed by the pipe jacking and shield-driven tunneling. If geological conditions are not suitable for the horizontal directional drilling crossing or the crossing distance is shorter (800 m or less) under the influence of minimum radius of curvature of the pipeline, the pipe jacking crossing method will be selected. When the crossing distance is greater than 800 m, the shield shall be used.
