Research on the Interaction between the Pile and Shield Machine in the Process of Cutting a Reinforced Concrete Pile Foundation

As the urban underground space environment gets more complex, cases of shield machines encountering and cutting through piles are becoming common. The interaction between cutter head pile foundation directly affects tunneling performance machine safety existing structure. To study machine, a calculation model force is established. A field test two was conducted rationality verified by comparing results with data. applied in project bridge Harbin Metro Line 3, China. operation parameters predicted compared results. Besides, impacts surface width eccentric distance on discussed. shows that there significant when cuts reinforced concrete piles, which causes obvious changes performance. number tools inside area has effect additional torque. torque fluctuates rotation increases increase tools. these determined factors such as layout head, distance, influence position each tool relative to area. increase, trend first increasing then decreasing reaches maximum value radius pile. moment width. complicated. this paper can provide reference for similar engineering.
