长江口北支上段水下平顺抛石固基工程施工技术探讨

Under the upper section of the Yangtze River estuary water smooth solid foundation of throw stone construction technology discussion

长江口北支凹岸段由于受上游来水和下游潮水的双向影响,造成局部江岸不断冲刷崩塌,深塘逼岸,危及大堤安全。海门市通过水下平顺抛石固基工程,辅以筑丁坝、抛石护坡等,有效地遏制了坍塌的进一步发展。

Concave branch of Yangtze River estuary coastal zone as a result of the bi-directional effects of upstream and downstream of tidal water,local Bank continue to scour collapsed,Shen Tang made shore, threatening dam safety. Smooth in haimen city through underwater rock-solid base project,supplemented by groining,RIPRAP,and effectively curb the collapse of further development.
