内河航道维护疏浚中岸坡稳定的控制办法

目前,维护疏浚已成为内河航道主要的养护方式之一。由于大多航道两岸的护岸建设年代久远,所以很难收集到完整的航道沿线护岸资料。为此,维护疏浚既要改善航道通航条件,又要保证航道沿线两岸岸坡稳定和建(构)筑物结构安全,成为维护疏浚设计和施工的重点和难点。结合上海市2010—2017年已实施的近百条内河航道维护疏浚项目的工程经验,总结维护疏浚过程中岸坡稳定控制办法。

Control measures for slope stability in maintenance dredging of inland waterway

At present,maintenance dredging has become one of the main ways of the conservation of inland waterways.Since most revetments on both sides of channels are old,it is difficult to collect complete data of revetments along channels.Therefore,maintenance dredging is necessary not only to improve the navigation conditions,but also to ensure the stability of the slope and the structural safety of buildings on both sides along channels,which are the key and difficult points in the design and construction of the maintenance dredging.Based on the experience of hundreds of inland waterway maintenance dredging projects implemented in Shanghai from 2010 to 2017,this paper summarizes the control measures for the slope stability during the maintenance dredging.
