摘要
结合南京纬三路过江通道冲刷坑抢险工程,对其监测技术组合特点进行分析,利用侧扫声呐、多波束和流速流向等监测技术手段全方位地对江底冲刷坑进行水文地形监测,快速有效地指导了施工,完成抢险,保障过江通道工程安全,可供类似工程参考。
Based on the emergency works to remedy the scour pits in the cross-river tunnel at Weisan Road in Nanjing, the paper analyzes the features of the monitoring technology and the scour pits in the river beds were all-round monitored hydro- logically and geographically by using side scan sonar, multi-beam echo sounder, flow velocity and direction, etc. to guide the construction, finish the rescuing works, and guarantee the safety of the river-crossing tunnel, which may provide refer- ence similar projects.
