A large number of concrete was used and resulted in destroying the ecology and environment of rivers. In recent years, ecological friendly and environment were also the considerations and ecological engineering method was applied in revetment constructing. Masonry structures and wire netting gabions were the most common method. However, the source of stones was limit and the strength of wires probably could not reach the fixed number of years. A precast building method was widely used and numerous structures were invented to fit in with ecological engineering method, such as types, size, capability and acquirement. Applying precast structure meets the requirement of the quality, dates of construction, and repairs the environment promptly. The research in this study suggested the application of precast building method on river bank protection.
