摘　　要：针对“长江口二号”曲线顶管底幕工法开展等比例试验,试验过程包括端板下放和管节推进两个主要过程.试验结果表明:曲线顶管底幕法可适用于沉船整体打捞;端板采用搅吸泵破除铁板砂的方法效率较低,后续应更换更高效的方式;3根管节中推进最大推力为2.2 MN,最大扭矩为28 kN·m.An equal scale test was conducted for the bottom curtain construction method of curved pipe jacking of“Yangtze River Estuary II”,which included lowering the end plate and advancing the pipe joint.The test results show that the curved pipe jacking bottom curtain method is suitable for the integral salvage of sunken ships.The method of using a stirring pump to remove iron plate sand on the end plate is inefficient,which should be replaced with a more efficient method in the future.The maximum thrust for propulsion in the three pipe joints is 2.2 MN,and the maximum torque is 28 kN·m.
