摘　　要：长江中游荆江河段是航道整治工程难度大、水沙条件变化复杂的河段。目前,该河段典型的航道整治措施为软体排加抛石与钢丝网护坡相结合的稳滩固岸结构,而施工中水下抛石形态的监控难度较大,缺少简便、直观、实用的软件与地形测量仪器相结合。本研究基于多波束河床地形扫描技术和三维虚拟仿真技术,开发一种水下抛石着床形态实时监控系统,对抛石前后的水下地形进行对比分析,及时反馈抛石施工区域漏抛少抛超过安全允许范围的情况并预警。研究成果将对水下抛石施工的质量控制具有重要的意义。The waterway regulation engineering is very difficult in middle Yangtze River which is called Jingjiang reach because of the special flow and sediment characteristics.The soft mattress with riprap and steel wire mesh protection structure is used as a typical waterway regulation measure to make the bank shore steady in recent years.Due to the lack of intuitive and practical software combined with the terrain measurement instruments,there are many difficulties in bed form monitor during the underwater riprap construction. This paper develops the realtime monitor system on the underwater riprap bed form based on the multi-beam terrain scanning and 3D-VR technology to compare the underwater terrain before and after the riprapping. The system can feed back the information once the riprap form is beyond the safe threshold value and warn the operator to do some remedial work.The research result will benefit the quality control of the construction of underwater riprap significantly.
