摘要
未经批准的河道采砂形成的砂坑会对河道岸坡甚至堤坡安全产生严重影响。对于河道管理,由于水下砂坑的隐蔽性,往往难以追踪其位置及规模形态,从而无法评估其对堤防及岸坡安全性的影响。为研究河道水下砂坑追踪技术及对堤防安全性的影响,结合工程,使用侧扫声呐、GPS-RTK及水下测深技术、Autobank分析软件等,对水下砂坑定位,并对砂坑规模形态进行测量,对堤防及岸坡的抗渗稳定性、抗滑稳定性进行分析计算,进而评估水下砂坑对堤防及岸坡安全性的影响。
The sand pits formed by unapproved river sand mining can have serious impacts on the safety of river bank slopes and even embankments.For river management,it is often difficult to track their location and scale form of underwater sand pits due to their concealment,and thus it is impossible to assess their impact on the safety of embankment and bank slope.In order to study the tracking technology of underwater sand pits in river channels and their influence on the stability of embankments,combined with the project,side-scan sonar,GPS-RTK,underwater bathymetry technology and Autobank analysis software are used to locate the underwater sand pits and measure the scale form of the sand pits,and to conduct seepage stability and anti-slip stability of embankments and bank slopes.Then the impact of underwater sand pits on the safety of embankments and bank slopes is evaluated.
