碎石回填是沉管安装完成后的一道重要工序，关系到沉管在海底的安全。港珠澳大桥隧道工程的碎石回填作业是在外海、深槽环境下进行，潮流、波浪情况复杂，且施工区处于航道区，船行波影响明显，增加了作业难度。为了保证碎石回填的精度，施工过程中从测深仪、多波束扫测等测量手段入手严加控制，有效保证了回填质量。
碎石迴填是沉管安裝完成後的一道重要工序，關繫到沉管在海底的安全。港珠澳大橋隧道工程的碎石迴填作業是在外海、深槽環境下進行，潮流、波浪情況複雜，且施工區處于航道區，船行波影響明顯，增加瞭作業難度。為瞭保證碎石迴填的精度，施工過程中從測深儀、多波束掃測等測量手段入手嚴加控製，有效保證瞭迴填質量。

The gravel backfill is an important process after the immersed tube installation, it relates to the immersed tube safety under the sea. The operation of gravel backfill in the Hongkong-Zhuhai-Macao Bridge tunnel project is in the open seas and in deep groove construction, the situation of tide and wave is complex. In addition the construction area is in the channel region, the significant influence of ship traveling wave increases the difficulty of the operation. In order to ensure the accuracy of gravel backfill, we kept the strict control for altimeter, multi-beam sweeping survey, which has effectively guaranteed the backfill quality.
