Abstract:This paper analyzes the adaptability of the auto-inserted retaining wall in the Changjiang waterway engineering relying on the high beach protection project in the Xinchang Zhoutian waterway. After one high flow season,the monitored results show that the lateral displacement of the retaining wall is limited to 20 mm and the maximum sedimentation is smaller than 15 mm. It reflects that the auto-inserted retaining wall can preliminary adapt to the complex flow scour condition and fulfill the design requirements,which builds a foundation for its further extending application in Changjiang waterway engineering.
