Calculation model of pipe-mud frictional resistance of pipe-jacking based on mud pressure and permeation characteristics

Key Points

• Frictional resistance is impacted by both mud pressure and the permeation characteristics of the surrounding soil.
• Key metrics include mud pressure levels, affecting the efficiency of pipe-jacking operations and affecting installation timelines.
• Assessment using a calculation model demonstrates the complex interactions between hydraulic properties and mechanical performance of the pipe-jacking system.
• Implications suggest that optimizing mud properties could lead to smoother installations and reduced operational costs.
