Abstract

Based on the salvage project of “Yangtze River Estuary II” ancient wreck, a coupled Eluer-Lagrangian (CEL) numerical analysis was conducted for the wreck salvage project adopting the curved beam based method using rectangular curved pipe jacking with an extremely small radius of vertical curvature. The dynamic evolutions of the driving force and the vertical displacement of the wreck were obtained and compared with the results of model test. The results show that the simulation results of the established numerical model agree well with the experimental data, which could predict the variation laws of movement and the driving force of the wreck. Pipe jacking of the last beam is the most dangerous, which requires a strengthened construction control. In comparison with sequential jacking from one side to the other, the left-to-right symmetric jacking can effectively reduce the disturbance to the wreck and its surrounding ground.

Key words： curved pipe jacking; wreck salvage; numerical analysis; coupled Eluer-Lagrangian (CEL) method
