Research on Application of Multi-beam Sounding System in Underwater Topographic Survey of Immersed Tube Tunnel

为获取某沉管隧道浮运航道及管节寄存区的水下地形地貌信息,本文采用R2Sonic(2024)多波束测深系统搭配高精度惯导分析设备对待测水域进行了大面积扫侧,同时对测深系统的工作原理、操作要点、技术参数、安装调试等进行了归纳总结,扫侧获得了目标水域水底三维信息模型,通过对模型的分析得到了开挖状况及水域高点具体方位。研究结果显示:高精度测深系统(R2sonic)在沉管隧道水下地形测量中发挥了不得替代的作用,本文的技术方法和注意事项可以为相关扫侧工作提供技术参考。

Inorder to obtain the underwater topography and geomorphology information of the floating channel and the storage area of a submerged tube tunnel,this paper adopts the R2Sonic(2024) multi-beam sounding system and high-precision inertial navigation analysis equipment to sweep the measured waters in a large area.Meanwhile,the working principle,operation key points,technical parameters,installation and debugging of the sounding system are summarized The three-dimensional underwater information model of the target water area is obtained by sweeping side,and the excavation condition and the specific orientation of the water area high point are obtained by analyzing the model.The results show that the high precision sounding system(R2sonic) plays an irreplaceable role in the topographic survey under immersed tube tunnel test The technical methods and precautions in this paper can provide technical reference for the relevant side sweeping work.
