摘　　要：以广东惠州西枝江连通东江新开河河道治理工程为例,结合河道实际及地质条件,提出悬臂式挡墙、重力式挡墙、预制混凝土桩等挡墙护岸形式,并从经济性、地下水位影响、土方开挖量、工程量、施工进度、透水性、外观造型等方面综合比较后,选用预制混凝土波浪桩挡墙形式;进而对该形式挡墙设计及施工要点展开分析探讨。结果表明,预制混凝土波浪桩属于绿色节能环保型结构,在提升挡墙结构抗弯承载力和耐久性的同时,使人工护岸与景观河道生态环境融为一体,社会效益和景观效益十分突出。Taking the Xinkai River channel treatment project connecting the Xizhi River to the Dongjiang River in Huizhou,Guangdong Province as an example,based on the actual and geological conditions of the river channel,this paper proposes retaining wall forms such as cantilever retaining walls,gravity retaining walls,and prefabricated concrete piles.After comprehensive comparison from aspects such as economy,groundwater level impact,earthwork excavation volume,engineering quantity,construction progress,permeability,and appearance,precast concrete wave pile retaining wall forms are selected;Further analysis and discussion will be conducted on the design and construction points of this type of retaining wall.The results indicate that prefabricated concrete wave piles belong to green,energy-saving,and environmentally friendly structures.While improving the flexural bearing capacity and durability of the retaining wall structure,they integrate artificial bank protection with the ecological environment of the landscape river channel,resulting in outstanding social and landscape benefits.
