【摘要】 近年来,由于各种因素使西江中下游河床下切,洪水的冲刷极易造成堤围险段深槽迫岸、座湾顶冲,危及堤围安全。为了有效监控堤围的变化情况,减少及避免堤围由于河床下切以及洪水冲刷造成的安全隐患,提高堤围的防护能力,通过多波束水下地形测量系统,对景丰联围进行水下地形测量,为堤围的科学监管提供实时准确的数据。更多还原

【Abstract】 In recent years,the middle and lower reaches of the Xijiang River bed under the cut for variety of factors,the floods washed away the embankment caused by highly dangerous section to force the deep offshore,endangering the safety of the embankment.In order to monitor the changes in the embankment effectively,reduce and avoid cutting under the river embankment due to erosion caused by the floods,as well as security risks and enhance protection of the embankment.With multi-beam system of underwater topographic survey, provide real-time scientific data to monitor the underwater topographic of Jingfeng United Embankment.更多还原
