摘　　要：以广西左江山秀船闸扩能工程为例,研究引航道高边坡施工开挖与支护施工技术。结合施工现场实际与引航道高边坡的特征,制定了高边坡施工的开挖和支护方法,以确保工程的安全性和可行性。研究结果表明,在左江山秀船闸扩能工程中采用该方法进行施工,两岸边坡的稳定性问题得到解决,确保了施工的安全进行,同时保障了既有航道的正常通航。Taking Shanxiu shiplock expansion project in Zuojiang,Guangxi as an example,this paper studies the construction technology of excavation and support of high slope of the approach channel.Combined with the actual construction site and the characteristics of the high slope of the approach channel,the excavation and support methods of the high slope construction are formulated to ensure the safety and feasibility of the project.The research results show that the stability of both sides of the slope can be solved by using this method in the capacity expansion project of Shanxiu shiplock in Zuojiang,which ensures the safety of construction and the normal navigation of the existing channel.
