摘要： 针对泥水盾构的弯曲管路进行三维建模,利用CFD-DEM耦合进行数值模拟,揭示泥浆携带卵石的运移规律,分析卵石沉积滞排的原因,探究卵石沉积对管道内流场的影响,为现场施工解决滞排问题提供优化指导。结果表明:滞排问题是由于低流速的泥浆提供的拖曳力太低,大量颗粒在管道弯曲处发生了沉积。管道内颗粒进入速度和排出速度将会达到动态平衡,管道弯曲度数越大,颗粒生成速度和排出速度达到动态平衡的临界点越晚,说明颗粒滞排越严重,滞排颗粒数量就越多。颗粒沉积导致有效过流面积变小,泥浆流速发生了明显分层,流场的分层更加不利于底部沉积颗粒的运移,加剧滞排问题。泥浆黏度越大,颗粒和泥浆发生剪切流动时的拖曳力越大,颗粒的平均运移速度越大。泥浆密度对颗粒的水平运移影响不大,但颗粒向上运输时,密度大的泥浆能够提供更高的浮力,有利于防治颗粒的滞排。
