摘　　要：以深圳至中山通道沉管隧道基槽工程为背景,建立二维水动力泥沙数学模型,采用现场实测资料进行验证,预测了大风过程基槽内的回淤分布。结果表明,基槽开挖后,最大下挖深度约30 m,大风过程引起的基槽淤积明显,回淤分布特征为中间大、两头小,最大淤厚为0.78 m。Based on the foundation tank project of the sinkhole tunnel in Shenzhen to Zhongshan channel,a two-dimensional hydrodynamic sediment mathematical model was established,and the field data were used to verify the results.The dredging distribution in the base tank was predicted.The results show that the maximum depth of excavation is about 30 m after excavation,the sedimentation of the foundation tank caused by the gale process is obvious,and the dredging distribution is characterized by a large middle and small two ends,and the maximum thickness is 0.78 m.
