摘　　要：为保障海底沉管隧道安装完成后,管节在海底可稳定、防冲刷、防锚,为管节提供足够的抗浮安全度等要求,需进行管节回填覆盖施工,确保管节安全稳定性。文章主要针对深中通道海底沉管安装后的回填施工精度研究,为了在外海环境下达到最终回填施工设计精度要求,需从施工工艺、回填材料、海流流速等多个方面加以控制,最终保障了回填精度的准确、提高了施工效率和材料利用率,为项目节约了成本,可为类似工程提供参考。In order to ensure that the submarine immersed tunnel can be stable,anti-scouring,and anti-anchor,and providesufficient anti-floating safety for the pipe segment after the installation,it is necessary to carry out the pipe segment backfillcovering construction to ensure the safety and stability of the pipe segment.This paper mainly focuses on the research on thebackfill construction accuracy after the installation of the submarine immersed tube in the Shenzhen-Zhongshan Link.In orderto meet the design accuracy requirements of the final backfill construction in the open sea environment,it is necessary tocontrol the construction from many aspects,such as construction technology,material control,and control of sea currentvelocity,so as to ensure the accuracy of backfill,improve the construction efficiency and material utilization rate,save costs forthe project,and provide reference value for similar projects.
