Abstract:In the middle and lower reaches of the Yangtze River channel regulation,the beach protection engineering with soft mattress as the main part is easy to cause beach surface hardening.In order to improve the habitat conditions of beach consolidation area,we propose an ecological channel construction technology combining the utilization of dredged soil and the protection of the beach based on the soil consolidation effect of hydrophilic vegetation,which is used in the engineering design of the second stage of waterway regulation from Xinzhou to Jiujiang channel.This technology uses the dredged soil to lift the beach surface,introduces the local flood resistant and hydrophilic vegetation,applies the degradable and pollution-free natural materials to assist in soil consolidation and erosion control,so as to ensure that the pioneer vegetation can develop stably to sufficient abundance,and finally achieve the stability of the beach.
